摘要：

In this paper, solvothermal synthesis of submicron nanocrystalline Y2O3: Eu particles with and without surface modifier (beta-alanine and Tween-80) is investigated. X-ray diffraction ananlysis confirms the one-step formation of Y-2(OH)(5)NO3H2O phase during solvothermal process and its conversion to Y2O3: Eu after heat treatment at 600 A degrees C. Fourier transformation infrared spectroscopy showed that C=C, C-C and C-H peaks are corresponded to the surface modifiers i.e. tween-80 and beta-alanine. Scanning electron microscopy and transmission electron microscopy images also showed that the modifier results in the particle morphology improvement from sheet-like to submicron spherical particles. Photoluminescence experiments indicated that the emission intensity increases due to the morphology modification.
