“…The second application concerns the simultaneous observation of Raman bands and emission lines, within the same range of the recorded spectrum in a crystal of LiNbO 3 doped with holmium. Lithium niobate (LN) is a well‐known material thanks to its outstanding properties and potential applications in piezoelectricity, acoustics, wave guiding, and nonlinear optics . It is a versatile material, the properties of which can be matched according to the nature and concentration of doping .…”

We show the interest in recording both Stokes and anti-Stokes Raman spectra in two peculiar applications. In one case, the comparison between these two parts of the spectrum, measured at one temperature only, allows to distinguish between first-and second-order phonon bands. In the second example, the difference between Stokes and anti-Stokes spectra provides separation between vibrational and emission lines. We describe the different stages needed in the measurements and data treatment.

“…However, the high electrical conductivity of congruent LiNbO3 complicates the use of this material above 400 °C. The stochiometric LiNbO3 is able to operate up to 600 °C [3]. Quartz is known to transform from α-phase into β-phase at 573°C [4].…”

Surface acoustic wave (SAW) sensors are steadily paving the way to wider application areas. Their main benefit consisting in the possibility of wireless interrogation with the radio frequency interrogation signal being the only energy source for the reradiated signal. This feature is getting more and more attractive with the growing demand in monitoring multiple industrial objects difficult to access by wired sensors in harsh environments. Among such wider applications, the possibility of making measurements of temperature, deformation, vibrations, and some other parameters at temperatures in the range of 300 °C-1000 °C look quite promising. This paper concentrates on specific features of the SAW resonator-based sensors operation at this temperature range. High-temperature influences the material choice and thus the properties of SAW resonators design peculiarities intended for use at high temperature. It is suggested that preferable designs should use synchronous resonators with relatively thick electrodes (10% of wavelength) based on Ir or Pt alloys while benefiting from the possibilities of specific designs that could reduce the negative impact of thick electrodes on the manufacturing in quantity. This solution benefits from lower resonance frequency scatter because of the automatic compensation of SAW velocity decrease due to electrode metallization ratio increase. This compensation originates from the resonance frequency increase that is related to the decrease of the Bragg bandwidth defined by the reflection. It is shown in modeling examples that the value of metallization ratio at which this compensation occurs is close to 65%-70%.

“…temperature sensors) or low temperature (ex. deicing sensors and actuators) implementations. , Since the material properties of films and the substrate in multilayered thin film systems are generally different, residual thermal stress will be generated during temperature changes, which leads to the dysfunction or failure of SAW devices (e.g., signal distortion in SAW sensors or damages such as delamination of film layers). − Furthermore, the properties of thin films depend on the method and conditions of their deposition on a substrate. The changing film system properties can lead to unpredictable behavior of MEMSs.…”
