Abstract
Nd3+-doped yttrium oxide nanoparticles (Y2O3:Nd) with cubic phase were obtained successfully by a glycine-nitrate solution combustion method. The results of Fourier transform infrared spectra (FTIR) showed that the –OH groups residing on the nanoparticles surfaces were reduced effectively by modifying with capping agent. The modified Y2O3:Nd nanoparticles displayed good monodispersity and excellent luminescence in N,N-dimethylformamide (DMF) solvent. Some optical parameters were calculated by Judd–Ofelt analysis based on absorption and fluorescence spectra. A relative large stimulated emission cross section, 1.7×10−20 cm2, of the 4F3/2→4I11/2 transition was calculated. Theses results show that the modified Y2O3:Nd nanoparticles display good luminescence behavior in organic media.
