摘要: MgO:Fe3+ (0.1-5 mol%) nanoparticles (NPs) were synthesized via eco-friendly, inexpensive and simple low temperature solution combustion route using Aloe vera gel as fuel. The final products characterized by SEM, TEM HRTEM. PXRD data Rietveld analysis revealed the formation of cubic system. influence Fe3+ ion concentration on structure morphology, UV absorption, PL emission photocatalytic activity NPs investigated. yellow with CIE chromaticity coordinates (0.44, 0.52) average correlated color value was found to be 3540 K which corresponds warm light NPs. control Fe3+. MgO matrix influences decolorization methylene blue (MB) under light. enhanced (4 attributed dopant concentration, effective crystallite size, textural properties, decreased band gap capability for reducing electron hole pair recombination. Further, trends inhibitory effect in presence different radical scavengers explored. These findings open up new avenues exploration Fe-doped eco-friendly water applications process display devices.
