摘要：Zinc strontium phosphate glasses doped with different trivalent praseodymium ion（Pr3t） concentrations are presented and their photoluminescence properties are investigated upon 442 nm excitation. With the Pr3tconcentration decreasing, the orange emission of Pr3t（1D2-3HJ） is enhanced steadily at the cost of its blue emission（3P1;0-3H4）. Monochromic orange emission of Pr3tions is obtained when the Pr3tdoping is reduced to 0.05 mol.%. The mechanism controlling the monochromatic characteristic of Pr3temissions is supposed to be associated with the phonon-aided nonradiative relaxation process of Pr3t：3Pj→1D2, which depends on the Pr3tconcentration as well as the phonon energy of the glass matrix. Sodium zinc tellurite and barium gadolinium germinate glasses with the lower phonon energy are used as reference hosts to clarify this mechanism, and the results obtained support this suggestion.
Zinc strontium phosphate glasses doped with different trivalent praseodymium ion (Pr3+) concentrations are presented and their photoluminescence properties are investigated upon 442 nm excitation. With the Pr3+ concentration decreasing, the orange emission of Pr3+ (D-1(2)-H-3(J)) is enhanced steadily at the cost of its blue emission (P-3(1;0) - H-3(4)). Monochromic orange emission of Pr3+ ions is obtained when the Pr3+ doping is reduced to 0.05 mol.%. The mechanism controlling the monochromatic characteristic of Pr(3+)a emissions is supposed to be associated with the phonon-aided nonradiative relaxation process of Pr3+:P-3(j).D-1(2), which depends on the Pr3+ concentration as well as the phonon energy of the glass matrix. Sodium zinc tellurite and barium gadolinium germinate glasses with the lower phonon energy are used as reference hosts to clarify this mechanism, and the results obtained support this suggestion.
