摘要: Abstract We have investigated the effects of uniaxial stress on fluorescence spectra Cr-doped forsterite, YAG and Y2SiO5. Large spectral shifts were found in all three crystals. In addition, pseudo-splittings emission observed. The large allow us to conclude that lasing these crystals originates from 3T2 state but not 1E state. also provide onformation which helps identify nature site being occupied by tetravalent chromium ions crystalline hosts.
