摘要：
The sensitisation with Yb3+ of other rare earth ions emission is intensively used in the last years for increasing excitation efficiency of infrared (diode laser) pumped solid state lasers. It proved as a good sensitiser for Pr3+ emission in various matrices. The spectral investigations for the elucidation of the nature of multisite structure of Pr3+ in, YAG and of the Yb3+ co-doping on Pr3+: YAG are presented in this paper. In Pr3+: YAG two types of multisites have been observed: perturbed Pr3+ sites by nonstoichiometric defects and strongly coupled Pr3+ - Pr3+ near neighbour pairs. Pr3+ spectra in Yb3+, Pr3+: YAG show new lines assigned to near neighbour Pr3+ - Yb3+ pairs and Pr3+ - Yb3+ - Yb3+ triades.
