Light emitting Y2-xO3:xTb3+ nano phosphor was synthesized using rapid gel combustion assisted process. The advantages of gel combustion base process have been exploited to produce nano particles in the pure homogeneous mixture formation. Synthesis conditions such as calcinations temperature and dopant concentration are varied in order to determine the exact optimum conditions for synthesizing Y2-xO3:xTb3+ nano particles with enhanced optical properties and smaller particle size. The prepared phosphor had predominant green colour due to magnetic dipole transition 5D4 → 7F5 of Tb3+ located at 543 nm. The nano crystals obtained through gel combustion method was characterized by using scanning electron microscopy (SEM), X-ray diffraction (XRD) technique and photoluminescence (PL) spectra.
