Description

Results of phase transition investigations of YVO4:Nd single crystal (vanadium in 5+ valency state) to YVO3:Nd crystal (V3+) as an effect of annealing of YVO4:Nd single crystal in hydrogen at 1200oC for 1h were presented. The refined lattice parameters obtained for the latter case, ao=5.2858(1) A; bo=5.5956(2) A and co=7.5824(2) A, are slightly larger only than those of YVO3. Valency change was also investigated for Cr ions due to transmission (Cr4+ → Cr3+) in Y3AL5O12:Cr laser single crystal and for Co, due to transition (Co2+ → Co3+) in LaGaO3 single crystal under influence of annealing in reducing and oxidizing atmospheres and gamma and proton radiations.
