Abstract

Optical spectroscopy and high pressure optical spectroscopy of the Cr-doped glasses of CaO-Ga2O3-GeO2 system have been used. The emission spectrum consists of the broad band at about 12700 cm-1 and the sharper band with maximum peak at 14495 cm-1 (the R line emission). We have attributed the R line luminescence to the octahedral strong field Cr3 sites in the microcrystallites whereas the broad band luminescence has been related to the chromium in the glassy phase.
