Abstract: Iron-doped tin(IV) oxide (Fe-doped SnO₂) nanoparticles have attracted considerable attention owing to their tunable optical, structural, magnetic, and electronic properties. This review synthesizes findings from recent studies investigating Fe-doped SnO₂ synthesized through sol–gel, hydrothermal, co-precipitation, combustion, and sputtering techniques. The literature demonstrates that Fe incorporation significantly influences crystallite size, oxygen-vacancy concentration, morphology, photoluminescence behavior, and band-gap energy. Most studies report retention of the rutile tetragonal phase with minimal impurity formation. The review highlights the relationship between synthesis conditions and material properties and discusses potential applications in photocatalysis, gas sensing, optoelectronic devices, and energy-storage systems.
