AbstractThis work concerned with effect of zinc oxide concentrating on the structural and optical properties of (MgO)1-x(ZnO)x thin films. (MgO)1-x(ZnO)x compounds were produced by mixing the two oxides powders accordance to the atomic ratios and compressed as pellets, these pellets were sintered in an oven at temperature1273K for five hours. Thin films from (MgO)1-x(ZnO)x compounds were obtained using pulsed laser deposition technique using Nd:YAG laser . The results of x-ray diffraction as well as UV-Visible- spectrophotometer measurements transmittance of (MgO)1-x(ZnO)x thin films were presented From the x-ray pattern it was observed reflection peaks (200) and (111) for cubic structure MgO and (100),(002) and (101) for ZnO wurtzite-phase reflections planes corresponding to the MgO cubic structure and ZnO wurtzite-phase while the prepared thin films with x content from 0 to 0.75 seemed to gather and rearranges their atoms until reveals some little peaks reveals at x=1.0 which give an indication to attend polycrystalline structure. The optical results declare a reducing of band gap i.e. red shift by the growth of ZnO incorporation in the prepared thin films.The data reveals that energy gap reduces from 4.0 eV to 3.20 eV . This affirms that the ablation of ZMO targets results in a tuneable band gap ZMO thin films. The calculated optical constants are greatly effected by ZnO incorporation in the prepared thin films.

Abstract(NiO) 1-x (ZnO) x compounds were prepared with different composition ratios. The compounds were obtained by mixing Nickle oxide and zinc oxide in the appropriate ratio and sintered at 1000°C for six hours. Pulsed laser deposition (PLD) method which is simple and inexpensive method was used to deposit (NiO) 1-x (ZnO) x thin films on glass substrate at ambient temperature. Structural, optical and properties were investigated. The structures investigation obtained from x-ray diffraction showed that the prepared of compound as well as thin films have polycrystalline structure where the diffraction peaks w ... Show More

AbstractThe compound Fe0.5CoxMg0.95-xO where (x= 0.025, 0.05, 0.075, 0.1) was prepared via the sol-gel technique. The crystalline nature of magnesium oxide was studied by X-ray powder diffraction (XRD) analysis, and the size of the sample crystals, ranging between (16.91-19.62nm), increased, while the lattice constant within the band (0.5337-0.4738 nm) decreased with increasing the cobalt concentration. The morphology of the specimens was studied by scanning electron microscopy (SEM) which shows images forming spherical granules in addition to the presence of interconnected chips. The presence of the elements involved in the super ... Show More

AbstractIn this study, the melting-cooling method was used to prepare the chalcogenide compound S60-Se40-X-PbX. Four samples were obtained by partial replacement of Selenium with Lead in the weight ratios x = 0, 10, 20, and 30, respectively. The materials were mixed separately, ground, placed in quartz ampoules, and heated to 500 degrees Celsius. After conducting several operations on the samples, their insulating properties were studied, represented by the real dielectric constant and the imaginary dielectric constant, and the electrical conductivity was measured as a function of the frequency. It was found that partial replacement plays an impo ... Show More

AbstractThis study includes the manufacture of four ternary alloys represented S60Se40-XPbX with weight ratios x = 0, 10, 20, and 30 by the melting point method. The components of each alloy were mixed separately, then placed in quartz ampoules and vacuumed out with a vacuum of roger that 10−4 Torr. The ampule was heated in two stages to avoid sudden dissipation and precipitation of selenium on the inner mass of the quartz tube. The ampoule was gradually heated and kept at 450°C for approximately 4 hours followed by 950°C for 10 hours.at a rate of 10 degrees Celsius, the temperature of the electric furnace ... Show More
