Abstract

Results of phase transition investigations of Nd:YVO₄ single crystal to Nd:YVO₄ single crystal in hydrogen at 1200 degrees C for 1h were presented. The refined lattice parameters obtained for the latter case, a₀ equals 5.2858(1) angstrom, b₀ equals 5.5956(2) angstrom and c₀ equals 7.5854(2) angstrom, are slightly larger only than those of YVO₃. Valency change was also investigated of Cr ions due to transition in Cr⁴⁺:Y₃Al₅O₁₂ and Cr³⁺:SrLaGa₃O₇ Ho and Pr ions in LiTaO₃ and Co³⁺ due to transition in LaGaO₃ single crystals under influence of annealing in reducing and oxidizing atmospheres and gamma and proton irradiations.
