摘要：
The origin of the superimposed emissions in the, green photoluminescence (PL) spectra of ZnO:Pr powders is discussed by comparing the PL excitation and photoacoustic (PA) spectra of ZnO:RE (Pr, Nd, and Ho) powders prepared by the evacuated sealed silica glass method. Assuming that the superimposed emissions are related to the shorter-wavelength-side light absorption of Pr3+, the absorption of Pr3+ is caused by the nonradiative recombination of excitons localized and delocalized at Pr3+ in the vicinity of the grain boudary and ZnO matrix.
