Abstract

Abstract: The structure, TEM morphology and photoluminescence(PL) of nanocrystallites Ln₂O₃;Eu (Ln=Gd, Y) phosphers were studied. Samples were prepared by glycerin(G)-nitrate(N) sollltion combustion synthesis. The particle size of Ln₂O₃ could be controlled by different ratio of G/N.the influences of mesoscopic effect on PL of Ln₂O₃: Eu, such as the red shift of the excitation peak,the broading of emission peaks, were discussed.

Key words: combustion synthesis, nanocrystallites, Ln₂O₃ :En（Ln=Gd, Y） phosphor, photoluminescence
