Abstract
Transmission and spontaneous photoluminescence excitation spectra of CsCdBr3:Tm (1 and 2.5 at % Tm) crystals have been studied under different optical pumping conditions. The results demonstrate that the anti-Stokes luminescence intensity in the thulium-doped crystals is higher at the higher doping level. We have determined the resonance wavelengths of IR photons for two-photon excitation of visible luminescence in CsCdBr3:Tm and identified the corresponding electronic transitions in thulium-related emission centers for Stokes and anti-Stokes luminescence.
