Structural, morphological and optical properties of Cd doped ZnO film grown on a- and r-plane sapphire substrate by MOCVD

The S concentration dependence of lattice parameters and optical band gap of a-plane ZnOS grown epitaxially on r-plane sapphire

“…2(a). The full width at half maximum (FWHM) of the rocking curve is about 1.4°comparable to 0.9°of Cd 0.11 Zn 0.89 O ð1 1 2 0Þ [28]. The relatively broadened FWHM reflects an enhanced mosaic structure of the ZnO 1Àx S x film.…”

Synthesis and enhanced photocatalytic property of feather-like Cd-doped CuO nanostructures by hydrothermal method

“…It was observed that the Bragg's angles (2θ) of (002) and (111) major diffraction peaks of doped CuO gradually and slightly shift towards lower angle with the increase of dopant, indicating the increase in lattice parameter values. The increase of lattice constant is due to the ionic radius of Cd 2+ (0.95 Å) is larger than that of Cu 2+ (0.73 Å) and therefore the substitution of Cu 2+ ions by Cd 2+ induces a lattice expansion [19]. Only when the doping amount exceeds 0.8 mmol, there are obvious impurity phase of Cd(OH) 2 is observed in the XRD patterns.…”

Optical and Structural Properties of ZnO and ZnO:Cd Particles Grown by the Hydrothermal Method

“…Many studies of doped ZnO:Cd have been performed on films; however, few of these works have investigated the properties of this combination and their influence on the formation of particles. The Cd doping of ZnO microstructures is important because Cd modulates the band gap of ZnO to a lower level, and it can suppress deep‐level emission, decrease the charge‐transfer resistance and increase the capacitance . This article presents a study of the influence of the cadmium concentration on the morphology and properties of ZnO particles.…”
