| Abstract: | In this paper,the photoluminescence of Pr 3+ in (REO) 3BO 3(RE=La,Gd,Y) excited by UV light has been studied.The results obtained indicate the influence of the host lattice,radius of positive ion and the covalency of the Pr 3+ -O 2- bond on the spectral character. The dependence of the 1uminescent intensities on the concentration of Pr 3+ in (REO) 3BO 3(RE=La,Gd,Y) and investigated the mechanism of concentration selfquenching of Pr 3+ in (REO) 3BO 3(RE=La,Gd,Y) have been analyzed. |
