“…9 A novel electrooptical dual-control color-changing device with excellent efficiency has been developed, utilizing composite electrodes composed of WO 3 /Cu and TiO 2 /NiO/CdS. 10 Peng et al synthesized dual-shell nanospheres consisting of hollow CuCo 2 O 4 -Mn 0.2 Cd 0.8 S, which exhibited improved photocatalytic hydrogen production activity. 11 The electrochemical performances have been improved by alloying CuS nanoparticles with CuCo 2 O 4 , as demonstrated by cyclic voltammetry (CV).…”

We investigated the influence of CdS on the structural and optical properties of nano ZnWO4 for optical applications. (1−x)ZnWO4/xCdS (x; 0 to 0.25) heterojunctions were formed and the structure and microstructure of the ZnWO4 and CdS phases developed were investigated using Rietveld refinement analysis for synchrotron X-ray diffraction data. Phase analysis revealed the phase percentage of the CdS phase is always less than the nominated value (x), implying merging of some Cd and S into ZnWO4. Raman spectra showed CdS peaks, confirming the existence of CdS. Scanning electron microscopy showed two distinct morphologies: plate-like particles (ZnWO4 phase) and spherical shape (CdS phase). UV–vis diffuse measurements revealed enhancement of absorbance and reduction in reflectance and transmittance, in the range 300–56 nm, as the amount of CdS (x) increased in the (1−x)ZnWO4/xCdS system. Band gap of the ZnWO4 phase reduced from 4.0 eV for x = 0.0 to 3.9, 3.6, and 2.9 eV for x = 0.05, 0.1, and 0.25, respectively. The highest refractive index values were obtained as the amount of CdS reached 0.05. Impact of alloying on linear and nonlinear parameters and emitted photoluminescence spectra was studied. Upon loading ZnWO4 with CdS, the PL intensity is greatly quenched and the whole spectrum is red shifted, from 480 to 540 nm. CIE chromaticity diagrams show that ZnWO4 sample without any doping exhibits a blue color while the doped system reveals green-yellow colors.
