Characterization and properties of CdO nanocrystals incorporated in polyacrylamide

Abstract

CdO quantum dots (QDs) incorporated in polyacrylamide were synthesized adding aqueous suspension of cadmium oxide in acrylamide:bisacrylamide copolymer. Optical properties of CdO nanocrystals were studied by optical absorption. The size ranges (2-3 nm) were calculated by the effective mass approximation.

Optoelectronic properties and temperature dependent mechanisms of composite-hydroxide-mediated approach for the synthesis of CdO nanomaterials

“…[1] Among these oxides, as a transparent conductive oxide (TCO); cadmium oxide (CdO) is a distinguished and versatile material for various optoelectronic applications particularly for sensitive sensors and solar cells. [2,3] CdO has other important applications in decorative glasses, enamels, Ni-Cd storage cells and also as catalysis in a number of hydrogenation and dehydrogenation reactions. [3] CdO is a well known n-type semiconductor with a room temperature direct bandgap of (2.2 -2.5 eV) and shows higher mobility value, necessary for high conductivity in transparent conducting oxides especially when low free carrier absorbance is desired.…”

Study Influence of Substrate Temperature on Optical Properties of CdS Thin Films Prepared by Chemical Spray pyrolysis

“…Thin films have a large surface area compared to their size and therefore exhibit different characteristics than those of bulk materials. In addition, the possibility of changing their optical and electrical characteristics depend on the methods of preparation and conditions, such as changing the type of additive or change the temperature of the substrate and type such as glass, quartz, silicon or aluminum and others [2].Thin-film technology is one of the most important technologies that has contributed to the development and study of semiconductors, which have recently gained considerable interest in nanotechnology researchers and have given a clear idea of many of the physical and chemical properties of these substances whose properties are difficult to obtain naturally [3]. The importance of semi-conductor materials in the scientific and industrial fields has been emphasized for its unique physical characteristics.…”

Structural, morphological and optical behaviour of PVP capped binary (ZnO)0.4 (CdO)0.6 nanoparticles synthesised by a facile thermal route

“…Other examples of suitable applications are clear electrodes, diodes and gas sensors, and these materials are widely used for these purposes [61][62][63]. In a similar way to the ZnO semiconductors, many different forms of CdO have been created at the nanoscale, such as cubes [64], thin films of nanoclusters [65], wires [66,67], nanoclusters [68], nanoparticles [69][70][71], crystals [72,73], nanorodes [74] and several more exotic structures such as CdO Rhombus-like nanostructure [75] and heterojunction nanofibres [76], among others [77]. The range of processing techniques applicable to CdO semiconductors mirrors those of ZnO, for example sonochemical and solvothermal processes [78], thermal decomposition [79], soft chemical methods [80], and evaporation techniques [81].…”
