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 4G5/2→6HJ (J=5/2, 7/2, 9/2) transitions of Sm3+ ion respectively.

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 4G5/2→6HJ (J=5/2, 7/2, 9/2) transitions of Sm3+ ion respectively.
