Nanoparticles of cadmium peroxide (CdO 2 ) were immobilized in poly 2,2 bithiophene (PBTh) to build photoactive inorganic/organic interfaces (I/O/I). Studies indicated that the CdO 2 initially immobilized in the organic polymer partially decomposed to a low band gap CdO. Therefore we refer to this mixture as CdO 2 /CdO. The CdO 2 /CdO/PBTh assemblies were subjected to optical and photoelectrochemical investigations in aqueous electrolytes containing acetate, nitrate, or phosphate. The equilibrium mixture of CdO 2 /CdO influenced the optical conductivity and dielectric contents of the assemblies. Furthermore, O 2 played an important role in the charge separation and transfer processes. The effects of an applied magnetic field were investigated and reported. The results were explained on the basis of formation of hybrid sub-bands due to band alignments between the assembly components. The photo-induced charge generation of PBTh was improved by occlusion of CdO 2 in the polymer as was evident by the greater photocurrent generated by CdO 2 /CdO/PBTh than that generated by PBTh.

“…Among the transparent conducting metal oxide semiconductor materials, CdO is an important n-type semiconductor material with direct band gap of 2.2-2.7 eV and indirect band gap of 1.36-1.98 eV [1]. CdO finds its potential applications in the field optoelectronics devices such as solar cells, phototransistors, photodiodes, transparent electrodes, catalysts and gas sensors [2][3][4][5][6][7][8][9][10][11]. Despite cadmium is toxic, CdO is widely used as a photo catalyst for effluent treatment [4,12,13].…”

Nanosized β-Cd(OH) 2 were successfully synthesized via simple chemical precipitation method using cadmium nitrate as a precursor in a solution of sodium hydroxide. The CdO nanoparticles were harvested from β-Cd(OH) 2 by thermal decomposition at 400°C. The structural, optical, and magnetic properties of the as prepared and annealed products of β-Cd(OH) 2 were studied. The morphology of the CdO nanocrystals annealed at 400°C analyzed by FE-TEM exhibits pseudo spherical morphology with sizes around 60 nm.

Optical Characterization of (CdO)_x(ZnO)_1-xComposite by Spray Pyrolysis Technique

Composite cadmium oxideszinc oxides, (CdO)x(ZnO)1−x, thin lms are grown with variable composition, x, by non-conventional spray pyrolysis technique from two separate cavities. X-ray diraction proves the formation of cadmium and zinc peroxides upon deposition. Further annealing in air causes a loss of crystallographic order in zinc oxide grains. Annealing does not aect the structure of cadmium peroxide. The optical constants are estimated by the Murmann exact equation from transmittance and reectance in the wavelength range between 400 and 2400 nm and show normal dispersion. Highest luminescent yield is assigned for samples with composition x = 0.5. Annealing causes increase in luminescence yield of (CdO)x(ZnO)1−x lms that could be explained in the framework of structural change.
