摘　　要：研究了磷酸盐玻璃中Ｔｂ３＋离子的敏化发光。结果表明：磷酸盐玻璃中Ｄｙ３＋，Ｃｅ３＋对Ｔｂ３＋产生敏化发光。确立了双掺Ｔｂ３＋和Ｄｙ３＋玻璃中Ｄｙ３＋→Ｔｂ３＋敏化发光的声子支助共振能量转移模型，双掺Ｔｂ３＋和Ｃｅ３＋玻璃中Ｃｅ３＋的激发能通过无辐射能量共振转移敏化发光，计算出Ｃｅ３＋→Ｔｂ３＋的能量传递效率。Sensitized luminescence of Tb 3+ in phosphate glass was studied.The results show that Tb 3+ luminescence is notably sensitized by Dy 3+ and Ce 3+ .In Tb 3+ and Dy 3+ codoped phosphate glass,the sensitized luminescence is caused by the phonon assisted the resonant energy transfer.In Tb 3+ and Ce 3+ codoped phosphate glass,Tb 3+ luminescence is sensitized through nonradiative energy transfer from Ce 3+ excitation energy,and the energy transfer efficiency of Ce 3+ →Tb 3+ is calculated,providing a basis for determination of optimal amount of rare earth elements as an additive.
