“…The higher value of optical band gap arises due to improvement in the crystallinity of CdO during microwave irradiation and this conrms the quantum connement. Several researchers [7,16,17,30] The refractive index (n) and extinction coecient (k) of the CdO samples (A, B, C) can be calculated by using following relation [32,33]: Figure 5 shows the dependence of the refractive index of the microwave irradiated CdO samples on wavelength. The refractive index of all samples lies between 2 and 5.99.…”

Cadmium oxide nanostructures were prepared by microwave assisted wet chemical technique at dierent time intervals. Results on structural, optical, and thermal properties of the CdO nanostructures as a function of the microwave irradiation were reported. The X-ray diraction data indicates that the sample showed perfection in the microstructural improvement as a function of microwave irradiation. Surface morphological changes with dierent time of microwave irradiation were recorded by transmission electron microscope and the particle size were found in the ranges from 5 to 30 nm. Chemical composition and thermal stability of the samples were analyzed by energy dispersive X-ray spectrum and thermogravimetric analysis, respectively. The band gaps were shifted towards the blue region due to the MossBurstein eect and it exhibited direct band transitions, which corresponds to optical band gaps of 3.924.20 eV and contrast behavior of optical properties of CdO nanostructure in UV and IR regions were registered. Room temperature photoluminescence spectra revealed that the intensity of luminescent emission tends to decrease with the increase in exposure of microwave irradiation.

“…The synthesis of undoped and doped CdO nanostructure with various dopants has been reported using different methods viz. chemical vapor deposition [7], chemical bath deposition [8], pulse laser deposition [9], ultrasonic spray [10], sol-gel [11], vacuum evaporation [12], spray pyrolysis technique [13], microwave assisted method [14,15], thermal evaporation [16] and electrochemical method [17]. However, above mentioned methods require high budget, post-synthesis of heating, high energy and huge time consumption to prepare undoped and doped CdO nanostructure.…”

“…The n-type conduction of undoped CdO was attributed to its native oxygen vacancies and cadmium interstitials [54]. CdO shows very high electrical conductivity even without doping due to the existence of shallow donors caused by intrinsic interstitial cadmium atoms and oxygen vacancies [1,46]. Researchers are trying to modify the synthesis procedure for CdO thin lms with the aim to improve chemical and physical properties of this material and try to synthesize nanostructures with well dened geometrical shapes (e.g., spheres, cubes, rods, wires, tubes, tetrapods, ribbons, disks, and platelets).…”

The optical properties of the CdO and Pt doped CdO thin lms synthesized by solgel technique were investigated. The lowest grain size value (81.34 nm) was found to be for CdO thin lm. The Pt doped CdO lms are transformed to clusters with nanoparticles. The transparency properties of the CdO thin lm is changed with Pt doping. The plots of refractive index indicate abnormal and normal dispersion regions. The refractive index values of the CdO thin lm are changed with Pt doping. The direct optical band gap values of the lms were changed with doping of Pt. The lm of 0.5% Pt doped CdO indicates the lowest optical band gap value (2.421 eV). The imaginary parts of the optical conductivity of the CdO and Pt doped CdO thin lms are higher than that of the real parts of the optical conductivity.
