在室温和LNT条件下，通过改变Pr ~（3+）的浓度（从0.01%到20%），测量了Pr ~（3+）在YPO_4中的~ 1D_2荧光的衰减时间和浓度猝灭。从理论上推导了1D 2态的辐射寿命和能量转移率。能量转移的可能机制进行了讨论，并推断其相对重要性在Pr 3+浓度范围内，我们的研究。
Decay time measurements and concentration quenching studies for the1D2fluorescence of Pr3+in YPO4are performed at RT and LNT by varying Pr3+concentration from 0.01% to 20%. From the studies the radiative lifetime of the1D2state and the energy transfer rates from it are deduced. The possible mechanisms of energy transfer are discussed and their relative importance in the Pr3+concentration range of our studies is inferred.
