“…From the extrapolation of the straight line portion of the curve on to the xaxis, the band gap value was found to be 3.15 eV for the prepared NiO nano particles. The calculated value of energy gap agrees well with the recent reports by Vivek et al The band gap value of NiO nano particles were found to get minimized through green synthesize root[13,21].…”

The numerous treatments for nano particles in the interdisciplinary field of biomedical self-discipline cannot be counted. Many researchers in biomedicine are intrigued by metallic-based nano particles. Several methods for synthesizing metal nano particles are under investigation, and green synthesis is considered a presumed choice due to its environmentally benign nature, safety from harmful chemicals, and economically favorable for synthesis. The target of the current research include the synthesis of nickel oxide nano particles (NiO NPs) through green route by using the extract prepared from the bark of Acacia Nilotica, and the analysis of its characteristics using XRD, SEM, EDAX, IR, UV-VIS, Photo luminescence spectra, microbial activity, mass loss scheme and electrochemical techniques. The diffraction analysis using X-ray (XRD) indicates the presence of NiO2 compound in the prepared nano particles. The Fourier transform Infrared spectroscopy (FTIR) confirmed the association of peaks with the C-H and Ni-O bonds present. The micro images from Scanning Electron Microscope (SEM) exhibited cubic cluster morphology on its surface. The UV Vis spectra showed a maximum absorption at 264 nm. The Photoluminescence spectrum demonstrated that the green synthesized NPs of NiO has a modified emission band due to the presence of oxygen deficiencies and induced surface imperfections. A study on its microbial application confirms that the prepared NiO NPs have a great potential for inhibition against bacteria such as S. aureus and E. coli and also instrumental against microorganic fungi, Candida albicans and A. niger. The mass loss system shows a restraint effectiveness of 93.68 percent in carbon steel and the electrochemical study supports the formation of a defensive protective layer on the cathodic locales of the carbon steel surface.

“…This fact is probably related to the overlapping cut-off wavelengths in the transmittance diagram of both oxides: zinc oxide and europium oxide 61 . Moreover, the lack of noticeable signal coming from Yb 2 O 3 in the sample of ZY_500 and ZY_600 thin films is caused by the overlapping absorption edges of ZnO and Yb 2 O 3 thin films, for which the absorption maximum falls at ~ 350–360 nm 62 . A noticeable trend in the dependence of the transmittance value on the calcination temperature is that the transmittance decreases with increasing temperature from 500 to 600 °C.…”

Hydrophilic photocatalytically active ZnO and ZnO thin films doped with Yb2O3 and Eu2O3 (rare earth metal oxide, REM) with optical transmittance exceeding 76% in the visible light range (λ = 550 nm) were prepared by a combination of sol–gel technique, spin-coating and high temperature thermal treatment at 500 and 600 °C. The thin films were tested using advanced research methods, i.e.: morphology and topography and fractures along with approximate thickness values were investigated on scanning electron microscope (SEM), chemical composition was determined using X-ray Energy Dispersive Spectroscopy (X-ray Energy Spectroscopy), topography and roughness were measured on atomic force microscope (AFM), water contact angle values were determined by sitting water droplet method, optical properties of the fabricated materials were investigated using UV/Vis spectrophotometer. The decolorization efficiency of rhodamine B in aqueous solution was analyzed over a period of 190 min, obtaining degradation rates of: 54.7% and 43.1%, for ZnO and ZnO coatings doped with ytterbium oxide and europium oxide, respectively. The roughness of thin hybrid coatings did not exceed 50 nm, ensuring effective absorption of electromagnetic radiation by the layers. The methodology presented by the authors for the fabrication of thin hybrid films characterized by the key properties of self-cleaning coatings can be successfully applied to coatings of photovoltaic panels and architectural glass structures.

A novel Al/CrO3/p-Si structure was built by help the spin coating technique. CrO3 thin layer has been characterized by the XRD, UV-Vis, SEM and AFM measurements. It has been observed that the CrO3 layer has amorphous structure with optical band energy value of 3.96 eV. The surface analysis of CrO3 layer by using AFM and SEM methods has been found to be rather rough that is not observed grains of any definite shape or size. Furthermore, some electronic quantities of Al/CrO3/p-Si junction by help the thermionic charge transport mechanism have been extracted by utilizing current-voltage (I-V) and capacitance-voltage data. Moreover, it has been seen that interfacial state concentration for the Al/CrO3/p-Si contact varied in the range of 8.05 × 1012 eV−1 cm−2 to 6.71 × 1011 eV−1 cm−2 in darkness, and 1.23 × 1013 eV−1 cm−2 to 3.82 × 1012 eV−1 cm−2 under the illumination condition. The photoelectric parameters of the Al/CrO3/p-Si contact under 100 mW/cm2 light illumination was studied by I-V measurement.
