“…As known, the addition of manganese cations can effectively increase the piezoelectric performance of perovskite‐structure oxides and BLSFs, thus, we chose manganese cations as modifiers. In addition to the excellent piezoelectric performance, for the applications of high‐temperature piezoelectric materials, thermal stabilities of their electrical properties are equally important for high‐temperature operations . However, no studies on the piezoelectric properties of BTF‐based oxides at increased temperatures have been reported.…”

Enhanced piezoelectric properties of Mn‐modified Bi₅Ti₃FeO₁₅ for high‐temperature applications

Bi5Ti3FeO15 (BTF) has recently attracted considerable interest as a typical multiferroic oxide, wherein ferroelectric and magnetic orders coexist. The ferroelectric order of BTF implies its piezoelectricity, because a ferroelectric must be a piezoelectric. However, no extensive studies have been carried out on the piezoelectric properties of BTF. Considering its high ferroelectric‐paraelectric phase transition temperature (Tc ~ 761°C), it is necessary to analyze the piezoelectricity and thermal stabilities of BTF, a promising high‐temperature piezoelectric material. In this study, lightly manganese‐modified BTF polycrystalline oxides are fabricated by substituting manganese ions into Fe3+ sites via the conventional solid‐state reaction method. X‐ray diffraction and Raman spectroscopy analyses reveal that the resultant manganese‐modified BTF has an Aurivillius‐type structure with m = 4, and that the substitutions of Fe by Mn lead to a distortion of BO6. The temperature‐dependent dielectric properties and direct‐current (DC) resistivity measurements indicate that the Mn ions can significantly reduce the dielectric loss tanδ and increase the DC resistivity. The piezoelectricity of BTF is confirmed by piezoelectric constant d33 measurements; it exhibits a piezoelectric constant d33 of 7 pC/N. Remarkably, BTF with 4 mol% of Mn (BTF‐4Mn) exhibits a large d33 of 23 pC/N, three times that of unmodified BTF, whereas the Curie temperature Tc is almost unchanged, ~765°C. The increased piezoelectric performance can be attributed to the crystal lattice distortion, decreased dielectric loss tanδ, and increased DC resistivity. Additionally, BTF‐4Mn exhibits good thermal stabilities of the electromechanical coupling characteristics, which demonstrates that manganese‐modified BTF oxides are promising materials for the use in high‐temperature piezoelectric sensors.

“…The detection limit for SF 6 in ultrahigh-purity Ar is 750 parts per quadrillion using the α-BiB 3 O 6 crystal and 10 parts per trillion for SF 6 in N 2 using the LiNbO 3 transducer. curve appear mainly as a result of simultaneous excitation of weakened resonance modes of the crystal, which typically have severalfold lower piezoelectric constants (10). Instead of a cell with plane parallel reflectors at each end, the adjustable reflector was a concave glass reflector with a focal length equal to the cavity length.…”

The amplitude of the photoacoustic effect for an optical source moving at the sound speed in a one-dimensional geometry increases linearly in time without bound in the linear acoustic regime. Here, use of this principle is described for trace detection of gases, using two frequency-shifted beams from a CO 2 laser directed at an angle to each other to give optical fringes that move at the sound speed in a cavity with a longitudinal resonance. The photoacoustic signal is detected with a high-Q, piezoelectric crystal with a resonance on the order of 443 kHz. The photoacoustic cell has a design analogous to a hemispherical laser resonator and can be adjusted to have a longitudinal resonance to match that of the detector crystal. The grating frequency, the length of the resonator, and the crystal must all have matched frequencies; thus, three resonances are used to advantage to produce sensitivity that extends to the parts-per-quadrillion level. (1) is that in a one-dimensional geometry, an optical beam moving in an absorbing medium at the sound speed generates a traveling compressive wave whose amplitude, in the linear acoustics limit, increases in direct proportion to the irradiation timewithout bound. Here, we report the application of this principle for trace detection of gases in a scheme where a pair of frequency-shifted laser beams produced by two acousto-optic modulators operating at slightly different frequencies are combined in space to produce a moving optical grating tuned to an absorption of an infrared active gas. The angle between the two beams is adjusted so that the fringe spacing of the grating Λ along with the frequency difference in the two beams Ω obeys the rule ΩΛ = 2πc; that is, the grating is tuned so that it moves at the sound speed with each antinode in the optical beam pattern moving synchronously with its photoacoustically generated compressive wave. It is shown here that, when a moving grating is produced in a cavity with two parallel reflecting surfaces resembling a laser resonator, two resonance conditions exist for generation of the photoacoustic effect-the first one when the grating motional speed matches the sound speed and the second one when twice the length of the cavity is an integral number of wavelengths of the sound wave. In addition, the method makes use of a resonant piezoelectric crystal as one of the reflecting surfaces of the detection cell so that the effects of three matched resonances are used to advantage to produce high sensitivity.The theory of operation of the detector is based on solution of the wave equation for pressure for a moving optical grating in a resonator. The wave equation for the photoacoustic effect in an inviscid fluid when heat conduction effects can be ignored (1, 5) is given bywhere c is the sound speed, t is the time, β is the coefficient of thermal expansion, CP is the specific heat capacity, and H is the optical energy deposited per unit volume and time. Consider a pair of phase-coherent, frequency-shifted optical beams directed at an angle to...

“…Furthermore, active studies were performed for new NLO crystal materials in the ternary Bi 2 O 3 -MO-B 2 O 3 system (MO is metal oxide), and a new non-centrosymmetric crystal Bi 2 ZnB 2 O 7 (BZBO) with orthorhombic symmetry was obtained [15,16]. To date, the α-BIBO and BZBO crystals have been successfully grown in labs, and their NLO and piezoelectric properties have been discussed [17][18][19][20][21]. However, there remains problems during the single crystal growth, and critical growth parameters have not been optimized yet, especially for the α-BIBO crystal.…”

The non-centrosymmetric bismuth-based oxyborate crystals have been extensively studied for non-linear optical, opto-electric and piezoelectric applications. In this work, single crystal growth and electro-elastic properties of α-BiB 3 O 6 (α-BIBO) and Bi 2 ZnB 2 O 7 (BZBO) crystals are reported. Centimeter-sized α-BIBO and BZBO crystals were grown by using the Kyropoulos method. High resolution X-ray diffraction tests were performed to assess the crystal quality. The full-width at half-maximum values (FWHM) of the rocking curves were evaluated to be 35.35 arcsec and 47.85 arcsec for α-BIBO and BZBO samples, respectively. Moreover, the electro-elastic properties of α-BIBO and BZBO crystals are discussed and summarized, based on which the radial extensional and the face shear vibration modes were studied for potential acoustic device applications. The radial extensional mode electro-mechanical coupling factors k p were evaluated and found to be 32.0% and 5.5% for α-BIBO and BZBO crystals, respectively. The optimal crystal cuts with face shear mode were designed and found to be (YZt)/−53 • (or (YZt)/37 • cut) for α-BIBO crystal, and (ZXt)/±45 • cut for BZBO crystal, with the largest effective piezoelectric coefficients being in the order of 14.8 pC/N and 8.9 pC/N, respectively.
