Предметные рубрики: UV-light generation Frequence-conversion K2Al2B2O7 crystal Composition ratio Mixed-crystals Growth KRbAl2B2O7 NLO properties Non-linear optical Non-linear optical properties Rietveld analysis of X-ray powder diffraction data Solubility limits Space Groups Structural parameter Ключевые слова (''Своб.индексиров.''): krbal2b2o7--solid solution--crystal structure--nlo properties Аннотация: The structures of K 2(1-x)Rb 2xAl 2B 2O 7, x = 0.25, 0.5, 0.75, have been determined in space group P321 through Rietveld analysis of X-ray powder diffraction data. The solubility limit in K 2(1-x)Rb 2xAl 2B 2O 7 crystals has been estimated as x similar to 0.83-0.9. Nonlinear optical properties of KRbAl 2B 2O 7 have been verified by powder Kurtz-Perry method. Mechanisms of structural parameter variation in K 2Al 2B 2O 7 crystal family have been discussed.
