“…With the rapid development of optoelectronic science and technology, multifunctional devices with modulated performance have attracted worldwide research attention (Benaissa et al, 2021;Leal-Perez et al, 2022). Lead-free perovskite ABO 3 -structured oxides are promising optoelectronic materials due to their noticeable ferroelectric, piezoelectric, optical nonlinearity, best compatibility and environment-friendly characteristics (Pattipaka et al, 2019;Guo et al, 2022).…”

Perovskite-type oxide SrSn1-xVxO3 thin films with different concentrations x = 0.1–0.9 were fabricated by using pulsed-laser deposition, and the effects of V doping on the structure, optical band gap and the third-order optical nonlinearity were systematically investigated. With the increase of x value, the lattice parameters of SrSn1-xVxO3 decrease from 3.997 to 3.862 Å gradually, while the optical band gaps firstly increase and then decrease with boundary at x = 0.3. The third-order nonlinear optical responses were studied via the z-scan technique. The closed-aperture measurements show a negative nonlinear refractive index n2, and the open-aperture measurements demonstrate a saturable absorption β. Both the n2 and β responses vary with the increase of V doping level. The metal-oxygen chemical bond along with the localized V5+Sn2+V5+ complex contribute to the enhancement of optical nonlinearity, and the highest value of third-order susceptibility χ(3) is observed in SrSn0.5V0.5O3 film.

Perovskite oxide vanadium-doped SrSnO3 (SrSn1−xV x O3) thin films with different concentrations x=0.1∼0.9 were fabricated by using pulsed-laser deposition, and the effects of V doping on the structure, optical band gap, and the third-order optical nonlinearity were systematically investigated. With the increase of the x value, the lattice parameters of SrSn1−xV x O3 decrease from 3.997 to 3.862Å gradually, while the optical band gaps first increase and then decrease with a boundary at x=0.3.

Dy-doped (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 ([(Ba0.85Ca0.15)0.99Dy0.01](Zr0.1Ti0.9)O3, 0.01Dy-BCZT) lead-free multifunctional ceramics were prepared by conventional solid-state sintering method, in which the effects of ceramic processing conditions were studied by structural analysis and performance characterization. The sintered 0.01Dy-BCZT ceramics have pure perovskite phase with composition near morphotropic phase boundary alongside apparent tetragonal distortion, high density and densified micro-morphology obtained via tailoring calcination and sintering temperatures. High resistivity, excellent dielectric performance and piezoelectricity were acquired, which were affected greatly by ceramic processing conditions. All samples exhibit excellent ferroelectric and strain properties, which approach intrinsic physical performance and have little dependency on ceramic processing conditions. Appearance of a strong broad emission peak, centred at ?442 nm, is related to the 4F9/2 ? 6H15/2 electron transition. Strong piezoelectric-fluorescent coupling effect was produced due to adding Dy and using BCZT piezoelectric matrix, which provides a promising choice in optoelectronic application field.
