摘要：

The exchange interaction is considered to play the dominant role in the quenching of D-5(0)-F-7(2) emission of Eu3+ in Y2O3 nanocrystals. Luminescence decay curves of D-5(0)-F-7(2) of Eu3+ in two sizes of nanocrystals were measured. We fit the luminescence decay curve by the Inokuti-Hirayama theory. The efficiencies of energy transfer of exchange interaction were calculated. The difference between theoretical and experimental curves of efficiency was analyzed.
