The zero-phonon electronic transitions in Cr(3+) and Ce(3+) impurity ions in a series of Lu3xY3-3xAl5O12 (0 < x < 1) garnet solid solution crystals were studied experimentally. It was observed that in contrast to the case of Ce(3+), the modification of zero-phonon R-line ((2)E-(4)A2) fluorescence spectra of Cr(3+) ions with changing x occurs in a discrete(More)
