Structural, Morphological & Optical Properties of (Cd0.90Zn0.1)S: AgPhosphor Synthesized by Conventional Solid-State Reaction Technique

Abstract

Here, we have discussed thatAg-doped cadmium zinc sulphide phosphor has been synthesized by high-temperature conventional solid-state reaction techniqueunder a nitrogen atmosphere. The influence of Ag (5 mol %)) concentrationon the crystal structure, morphology, and optical properties of (Cd_0.90Zn_0.1)S crystals has been investigated by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and photoluminescence (PL) emission spectroscopy. The PXRD pattern have revealed a hexagonal crystalline phase. The morphology images have confirmed the microcrystalline behaviour and better connectivity with grain. The photoluminescence spectra have obtainedby irradiating the samples with 345-nm UV light. The effects of 5 mol % concentration of silver ions on the photoluminescence spectra of thesynthesized phosphor have investigated in detail.
