CdxZn1-xS/ZnO with x = 0.54, 0.58, 0.62, 0.68 and 0.75 was successfully tuned by altering the molar ratio of Na2S and Na2S2O3. Sole sulfur source Na2S or Na2S2O3 could only generate Cd0.5Zn0.5S or CdS/ZnO, respectively. The in-situ co-growth of CdxZn1-xS and ZnO makes them combine...

However, the current photocatalytic efficiency is unsatisfactory due to the low ...
The Group II-IV semiconductors are widely used in solar cells based on thin films, among these semiconductors the ternary CdZnS. In this work, we have deposited the CdxZn1-xS thin films on glass substrates by using chemical bath deposition. The synthesized CdZnS thin films were deposited by ...
Volvox-like CdxZn1−xS solid solutions with a cubic zinc blend structure were synthesized through a template-free ethylene glycol process. Cd(Ac)22 H2O, Zn(Ac)22 H2O, and thiourea are used as the starting materials and dissolved in ethylene glycol. These reaction precursors and solvent ...
A novel and simple chemical reduction route at room temperature is described to synthesize nanocrystalline CdS, ZnS, and CdxZn1-xS. In the method, anhydrous CdCl2, or ZnCl2, S, and KBH4 powders react at room temperature in various organic solvents, and the effect of the solvent on the quali...
The structural, electronic and optical properties of CdxZn1−xS alloys have been studied using the first-principles plane-wave pseudopotential (PP) method within the local-density approximations (LDAs). The effects of composition on lattice constants, bulk modulus, band gap, dielectric functions, re...
