PXRD analysis reveals a hexagonal wurtzite structure for all the synthesized samples. UV–visible measurements demonstrate a reduction in the bandgap of ZnO with an increase in Fe concentration. The ZnO and Fe-incorporated ZnO NPs are studied for the degradation of organic textile dye under visible light irradiation. All the nanoparticles are thoroughly investigated using impedance and dielectric measurements in the frequency range of 20 Hz to 1 MHz. The results obtained are compared, interpreted, and presented in this paper. © The Author(s), under exclusive licence to Springer Nature B.V. 2024.Atomic emission spectroscopyDoping (additives)Field emission microscopesMetal nanoparticlesPhotocatalysisPhotodegradationSurface dischargesSynthesis (chemical)Vat dyesX ray powder diffractionZinc SelenideDielectric effectsDielectric responseFe dopingPhotocatalytic efficiencySolution precipitationSynthesisedTextile dyesVisible lightX- ray diffractionsZinc oxide nanoparticlesZnO nanoparticlesdyeirontextile dyeunclassified drugzinc oxide nanoparticleArticleconcentration (parameter)degradationdiffuse reflectance spectroscopyelectric conductivityfield emission scanning electron microscopyirradiationparticle sizephotocatalysisprecipitationsurface propertysynthesis
