“…The spectrum of the samples, show a band observed at (3350-3450) cm-1 assigned to the v-OH which refers to the presence of H2O. Whereas, the presence of a band in the range 1624-1635 cm -1 is due to bending vibration of adsorbed H2O molecules 19 . Hence, the presence of an OH band in the spectrum is owing to chemically and physically adsorbed water molecule on the surface of nanoparticles 20 .…”

Effect of transition metal dopant on structural, optical, thermal properties, and antimicrobial activities of synthesized zinc oxide nanoparticles (ZnO NPs) were investigated in this study. undoped, cobalt, and nickel doped ZnO nanoparticles are successfully synthesized using chemical co-precipitation method. The structure and morphology of these nanoparticles are characterized using X-ray diffraction (XRD), atomic force microscope (AFM), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), as well as an appropriate physical measurement; (Vibrational and electronic) spectroscopy. The Results obtained from XRD indicate that the particles are possessed in wurtzite structure , SEM and AFM studies reveal that the particle size is in the 45-65 nm range. The EDS confirmed the Zn, O, Co, and Ni as major elements of as-synthesized nanoparticles. Ultravioletvisible (UV-Vis) spectra show that doping Co and Ni, lead to an increase in the absorption edge wavelength and a decrease in the band gap energy, Fourier-transform infrared (FT-IR) spectra give the presence of functional groups and chemical bonding as well as doped sub-lattice. To measure the biological activity and potential antimicrobial efficiency of these undoped, Co, and Ni-doped ZnO nanoparticles on the Candidates.

“…The results of these studies have revealed much about the general nature of the II-VI semiconductors and the feature of chemical stability of the higher energy gap materials at room temperature offers an immediate advantage over the unstable III-V phosphides. Type II-VI semiconductors, in their broadest sense, include compounds formed from elements of group II and group VI of the periodic table 3 . Generally Cadmium oxide is a II-VI n-type semiconductor and has interesting properties like large band gap, high electrical conductivity and high transmission in the visible region 4 .…”

Cadmium oxide has found its applications in various areas of research such as solar cells, phototransistors, photodiodes, transparent electrodes and gas sensors. In the present work CdO nano particles were successfully synthesized from cadmium acetate through thermal decomposition at high temperatures by adopting the solid state reaction. The prepared nano particles are subjected to ball milling for different timings. From X-ray diffraction it was found that the particle size decreases for an increase in the time of ball milling. The structure and the elemental composition were analyzed using SEM with EDAX. The optical band gap of CdO nano particles were determined using UV-Vis absorption spectroscopy. The thermal properties were determined using TGA/DTA analysis.

Bismuth Ferrite (BFO) intercalated Montmorillonite clay (MMT) nano composites have been synthesized using ascorbic acid and its optical behavior has been investigated. The characterization of BFO-MMT nano composites has been done using FT-IR, UV-visible, X-ray diffraction (XRD), Scanning Electron Microscope (SEM). Also, electron hole recombination has been investigated by photoluminescence (PL). From the analytical techniques, it has been found BFO entered into the layered host which was proved by elongation of basal plane and therefore agglomerated BFO was formed. The particle size can be calculated by Scherrer formula, is in good agreement with SEM. The strong absorption band in UV-Visible region attributed BFO nano composites can be used for photo catalytic degradation of Rhodamine-B (Rh-B). From the electrochemical studies, BFO-MMT clay nano composites showed a good specific capacitance at a scan rate of 10 mVs −1 .
