中文摘要：
采用固相反应法制备了Pr3＋,Yb3＋共掺杂的YPO4下转换发光粉体,并在450 nm光激发条件下,研究了Yb3＋不同摩尔分数（0%,1%,2%,4%,20%,30%）对转光效率的影响。结果表明：不同Yb3＋浓度的样品,其荧光峰强度不同,这可能是由于Pr3＋-Yb3＋之间Yb3＋浓度不同存在能量传递效率差异的原因。研究也发现了样品的下转换发光,其能量传递过程为：Pr3＋：3P0→Yb3＋：2F5/2＋2F5/2。荧光光谱测试结果表明,Yb3＋的最佳掺杂摩尔分数为2%。Pr3＋,Yb3＋共掺杂的YPO4材料在提高太阳能电池光电转换效率方面具有潜在的应用。
英文摘要：
Pr3＋,Yb3＋ co-doped YPO4 downconversion phosphor powders were prepared by solid state reaction.When excitation at 450 nm,the effects of different Yb3＋ mole fractions（0%,1%,2%,4%,20%,30%） on the conversion efficiency are studied.Results shows that because of the difference of energy transfer efficiency between Pr3＋ and Yb3＋,the samples with various Yb3＋ doping concentrations have different fluorescence intensity.It is also found that the energy transfer process of the downconversion luminescence in samples is Pr3＋：3P0→Yb3＋：2F5/2＋2F5/2.From photoluminescence spectra measurement,the optimal doping mole fraction of Yb3＋ is 2%.The results indicate that Pr3＋,Yb3＋ co-doped YPO4 downconversion phosphor is a kind of potential material which may be used to improve the solar cell efficency.
