摘要: Praseodymium- and bismuth-substituted gadolinium gallium garnet (GGG) layers have been prepared by liquid-phase epitaxy on (111)- (110)-oriented GGG substrates. By an investigation of linear dichroism Pr/sup 3 +/ -transitions, the supercooling dependence dodecahedral site selectivity in Pr-substituted can be shown to differ considerably for (110)- (111)-epitaxial layers. An increase insite with is found (111) while it constant (110) The long-wavelength /sup 1/S /sub 0/ ..-->.. 3/ P/sub 1/-transition B/sub 1/ ion has utilized detect (110)oriented Bi-substituted
