Abstract: We report fluorescence, magneto-optics and light absorption studies of Er3+ in Ca3Ga2Ge3O12 both at room and liquid-helium temperatures. We found that several sites are occupied by the Er3+ ions, which substitute Ca2+, corresponding with different charge compensation in the Er3+ neighbourhood. Here we present the complete optical study of the most populated of these sites. We compare our results with previous ESR experiments in similar samples and other rare-earth optical experiments in the same host. (C) 1998 Elsevier Science Ltd. All rights reserved.
