中文摘要	beta-ga2o3: cr single crystals were grown by floating zone technique. absorption spectra and fluorescence spectra were measured at room temperature. the values of field splitting parameter dq and racah parameter b were obtained by the peak values of absorption spectra. the value 10dq/b=23.14 manifests that in beta-ga2o3 crystals cr3+ ions are influenced by low energy crystal field. after high temperature annealing in air, the cr3+ intrinsic emission was enhanced and the green luminescence disappeared. the strong and broad 691 nm emission was obtained at 420 nm excitation due to the electron transition occurred from t-4(2) to (4)a(2). the studies manifest that the beta-ga2o3 crystals have the potential application for tunable laser.
