Abstract: Absorption,excitation and emission spectra as well as decay time measurements at 10,77,and 300 K were performed for Ga3Gd3Sc2O12 garnet single-crystal doped with Cr3+ and Nd3+ ions.Strong reabsorption of Cr3+ emission by Nd3+ absorption lines was observed.The assignments of f-f and d-d transitions were proposed.The broad emission band of chromium ions is an indication that weak/intermediate crystal field strength is present at the Cr3+ site.
