Structural and dielectric properties of Cu-doped α-ZnMoO4 ceramic system for enhanced green light emission and potential microwave applications

摘要: In this article, the synthesis of Zn1-xCuxMoO4 ceramic system was carried out by a solid-state reaction route, and their structural, morphological, optical properties were investigated. The samples characterized X-ray diffraction, scanning electron microscopy, Raman spectroscopy, FT-IR UV–Vis spectrophotometry. Structural analysis confirms formation triclinic structure with space group P $$\stackrel{-}{1}$$ point symmetry C1 without any secondary phase formation. decrease in effective nuclear charge introduction Cu2+ ion decreases bandgap from 3.57 to 2.78 eV. potential application visible (green) region electromagnetic spectrum is supported reduction bandgap. increasing concentration accompanied Photoluminescence peaks being shifted toward larger wavelength side, covering broad range 300 600 nm. luminescence emission spectra that happened ZnMoO4 occurred due electronic transition between (MoO4)2− complexes or Mo4d O2p states. Hakki–Coleman method applied for study microwave dielectric parameters shows increase eobs 8.35 12.52 simultaneous loss (tan δ) 0.01 0.005, respectively. corresponding quality factor (Q $$\times$$ f) calculated. observed high-quality could be used as high signal speed materials.
