Luminescence and scintillation properties of YAG:Pr

In this paper, we report on the scintillation and spectroscopic properties of YAG crystals activated with Pr/sup 3+/ ions. The light yield of this material was found to be dependent on the level of activation. Best results are achieved for nominal Pr/sup 3+/ concentration of 0.24 at.%. Spectroscopic results reveal effects readily explained in the frame of the recombinational model of YAG:Pr scintillation.
