Inorganic Al2O3 nanopowder was synthesized by aldo-keto gel method. The prepared sample was characterized by X-ray powder diffraction (XRD) and it is found that the average particle size was 31 nm. The Debye-Scherrer’s formula was used to calculated standard particle size. The ultraviolet-visible (UV-VIS) spectra show strong absorption in UV region of 224 nm with weak absorption bands in the region of 300–350 nm. The photoluminescence (PL) properties were studied by fluorescence spectrophotometer (F-7000) indicating the emission of radiation of 399 nm when nanopowder excited by 224 nm radiation. The characteristic band gap of Al2O3 nanopowder was found to be 4.7 eV by aldo-keto gel method.
