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