摘要：

The nanocrystalline of Y2O3:Eu3+ red Phosphor has been studied. The result shows that the maximum excitation spectrum of Y2O3:Eu3+ peaks at lambda(ex) = 252.6 nm, while the maximum emission spectrum peaks at lambda(em) = 613.4 nm under 254 nm excitation. The luminescence intensity increases with the growth of agglomerate size, adding assistant melting agent and increasing the sintering temperature. The hanging-bonds and the defects on the surface of nanocrystalline Y2O3:Eu3+ particle were removed and its luminescence intensity was increased by the coating process.
