Spherical nanoparticles of Y2O3:Eu3+ with cubic phase has been synthesized by solution combustion method using glycine as chelating agent and urea as fuel. The 1200 °C annealed sample yield intense red luminescence at 610 nm corresponding to 5D0→7F2 transition of Eu3+ ion under vacuum ultraviolet (VUV)/ultraviolet (UV) excitation. Furthermore, the luminescence decay time of the 5D0→7F2 transition at 610 nm was also calculated against the 147 nm VUV excitation and found to be ~ 4 ms. These highly luminescent spherical nanopartcles of Y2O3:Eu3+ seems to be one of the promising candidates for modern age display devices. Copyright © 2011 VBRI press.
