Lanthanum-gallium tantalate: Heterogeneity and point defects

Year: 2015

Type: conference-paper

Abstract: In this study the important factors having influence on the occurrence of color centers (crystal growth conditions and postgrowth effect on the crystal) in LGT (La 3 Ga 5,5 Ta 0.5 O 14 , langatate) crystals were investigated. In order to check the model of defect formation in crystals of langatate the effect of ionizing radiation on the spectral dependence of the attenuation coefficients of langatate crystals was studied. The ionizing radiation doses were 10 11 – 10 15 cm −2 . The optical homogeneity was evaluated by interferometric method on a Fizeau interferometer. The refractive indices of the crystals obtained in different atmospheres and after the isothermal annealing were measured by the prism method.
