摘要	Nanocrystalline Y2O3: Eu powders doped with different metal ions M (M: Li+, Na+, K+, Mg2+, Sr2+, Ba2+, B3+ and Al3+) were synthesized by glycine combustion. Their structure and luminescent properties were studied and compared with each other. The nanocrystalline Y2O3 were cubic in symmetry by XRD pattern. It can be concluded that codoping can modify the size and crystallinity of nanoparticles. As a consequence, the luminescent properties such as the fluorescent intensity, lifetime of D-5(0) - F-7(2) and the location of charge transfer band (CT band) vary with co-dopants. The variation depends more strongly on the crystallinity of nanoparticles than the size. Especially, in Li+-doped Y2O3: Eu nanoparticles, the emission intensity improves as large as three times than that of undoped ones.
