Abstract

The non-linear optical crystal Bi2TeO5 is a good host for several cations with segregation coefficients close to or larger than unity. Bi2TeO5:Er was the first rare earth doped crystal that was grown and studied. Eight Er3+ related transitions were identified in the absorption spectra, from the 4I15/2 ground state. All the expected Stark components of the observed transitions were detectable at 10 K. Further splitting of the lines related to the different Bi sites occupied by Er. Excitation from higher Stark levels of the ground state was detected at 200 K and above. Erbium related luminescence was observed in the doped crystals after photo-excitation to the 4F5/2, 4F7/2, 2H11/2 and 4S3/2 levels.
