“…The weight loss of TGA curve up to 100°C mainly corresponds to evaporation of water. In addition, the enormous weight loss at 346°C indicates emission of the sulfur (S) ions from the CdS lattice or disassociation of the CdS [41]. After that, ([346°C) a significant weight gain is observed in the TGA curve as shown in the Fig.…”

Mn 2? doped (1-5 and 10 %) CdS nanoparticles have been synthesized by the chemical precipitation method using polyvinylpyrrolidone as a capping agent. The particle size, morphology and optical properties have been studied by X-ray powder diffraction, transmission electron microscopy, UV-Visible and photoluminescence spectroscopy. Powder diffraction data have confirmed that the crystallite size is around 2-5 nm. The band gap of the nanoparticles has been calculated using UV-Visible absorption spectra. An optimum concentration, Mn 2? (3 %) has been selected by optical study. The functional groups of the capping agent have been identified by fourier transform infrared spectroscopy study. The presence of dopant (Mn 2? ) has been confirmed by electron paramagnetic resonance spectroscopy. Thermal properties of CdS:Mn 2? have been analyzed using thermogravimetric-differential thermal analyser. The electrochemical properties of the undoped and doped samples have been studied by cyclic voltammetry for electrode applications. In addition, magnetic properties of Mn 2? doped CdS have been studied using a vibrating sample magnetometer.

“…So the deposited films may have different structures and chemical composition. It is known that annealing process of CdS targets in pure nitrogen resulted in a reduction in the targetÕs weight [15]. In the present work, we studied the effects of target annealing temperature up to 500°C in air.…”

“…Hence, switching from conventional light sources to SSL 66 would represent a massive energy saving of more than 50% [6,8]. 67 Both organic [9] and inorganic [10] materials have been proposed 68 for highly-efficient SSL. In terms of optical properties, SSL needs a 69 broad-band luminescence in the wavelength interval ranging from 70 400 nm to 750 nm.…”
