For the first time green route method was used to synthesize pure and Mg 2+ (1-11 mol%) doped Y2O3 nanophosphors by using Aloe vera leaves extract as a fuel. The final product was well characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and diffuse reflectance spectroscopy (DRS). The PXRD pattern reveal that the formation of single phase, cubic structure of Y2O3 with crystallite sizes ~25 nm. The SEM results showed porous and agglomerated structures. TEM images showed the crystallite size of the material and were found to be around ~ 25 nm. DRS studies revealed that the band gap of the nanophosphors was found to be around 5.82 to 5.87 eV.
