| Abstract: | We have determined the starting mixture composition and process parameters for the growth of bulk, uniform Li2Mg2(MoO4)3 and Li2Mg2(MoO4)3:Co2+ (1 at %) crystals by a modified Czochralski technique at low temperature gradients (<1°C/cm). The 1500-, 750-, and 600-nm bands observed in the optical absorption spectra of the Li2Mg2(MoO4)3:Co2+ crystals are due to the Co2+ ions, which have a 3d 7 electron configuration and substitute for Mg2+. |
