Abstract

Europium trivalent (Eu\(\mbox{} ^{3+}\), 2%) doped Y\(_2\)O\(_3\) nanophosphors were synthesized by solgel method and annealed at temperature 600 \(^\circ\)C and 900 \(^\circ\)C. The phosphors were characterized by XRD, FTIR, UV-visible and PL spectroscopy. The average crystal size was in the range of 10-26 nm. FTIR spectra show that the intensities of all impurity peaks get reduce with increasing annealing temperature. The band gap was determined from the diffuse reflectance (DR) spectra using the K-M function. The photoluminescence spectra were describe by well known \(\rm ^5D_0\)-\(\rm ^7F_j\) transitions \((J=0,1,2,3,4)\) of Eu\(^{3+}\) ions.
