Abstract

Y₂O₃:Sm³⁺ (3 mol%) nanophosphors was synthesized by solution combustion technique using Aloe Vera gel as a fuel. The pristine and E-beam irradiated samples were subjected to powder X-ray diffraction studies (PXRD). Pristine sample reveled the formation of highly crystalline cubic phase of Y₂O₃. Whereas the E-beam irradiated sample showed decrease in crystalline nature by the creation of defects. Photoluminescence (PL) spectra taken for pristine and E-beam irradiated Y₂O₃:Sm³⁺ nanophosphors showed characteristic emission peaks at 570, 608 and 656 nm corresponding to ⁴G_5/2→⁶H_J (J=5/2, 7/2, 9/2) transitions of Sm³⁺ ion respectively.
