Mg1-xO:Fex3+(x=0,0.1,0.2,0.3,0.4) nanophosphors were prepared via solution combustion synthesis (SCS) technique were characterized using powder X-ray diffraction (XRD), Fourier Transformation Infrared (FTIR) Spectroscopy, Photoluminescence (PL) and Thermoluminescence (TL). XRD analysis confirmed the existence of cubic structure. The average crystalline sizes calculated by using Debye Scherer’s formula found to be around ∼32-39 nm in these samples. FTIR spectra also confirmed the phase purity of the samples. PL spectral analysis revealed the presence of the surface defects namely oxygen vacancies, F-centers/F+-centers. TL intensity decreases by doping of Fe content in MgO nanophosphors. Even at high gamma doses there is no significant increment in TL intensity of Fe doped MgO whereas in case of MgO pure nanophosphor TL intensity increases with increasing Gamma doses.
