CuAlS_2 thin films of thicknesses 118 \pm 5 nm were deposited on glass substrates using chemical bath deposition technique. The details the preparation method are well described. is relatively simple and easily controlled sufficient to produce large area good adherence substrate films. Effect annealing temperature T_a structure, optical properties investigated. structures studied by X-ray diffraction FTIR spectrophotometer. ascertained UV-VIS spectrophotometer (wavelengths ranging between...

In this research, anti-reflection coatings consisting of single and double layers were designed in the IR (8 – 14μm) region to reduce unwanted reflections germanium (Ge) substrate. The reflectance Ge substrate was about 36% per surface. These values reduced reasonably by using layer anti-reflection. used promoted their performance changing thickness refractive indices. results indicated that suggested structures are very efficient reducing substrates selected region. antireflection ZnSe,...

In this paper, photoelectrochemical etching of the n-type silicon (n-Si) wafers is used to prepare porous (PSi) with current density 10 mA.cm[Formula: see text] for min. Moreover, structural and morphological properties n-PSi were analyzed by using XRD AFM, FTIR PL. patterns PSi show that films are single-crystalline, cubic structure. The major peak characteristics allocated plane (004). atomic force microscope image distribution chart grains displayed grain sizes −8.98. a powerful...

Abstract In this research gold nano-particles (AuNPs) was synthesized by electrolysis Technique. Au thin films were deposited on the silicon and borosilicate glass at a Temperature (80 °C) dropcasting method. Structural, optical topographic properties of prepared NPs estimated UV-VIS spectrometer, TEM, AFM, XRD diffraction. The open circuit Voltage (V oc =2.8 mV) Short-circuit density (I sc =5mA). This resultant relive that fill factor (F.F) conversation efficiency (η), 32% 9.3% respectively.

Abstract In this study gold nanoparticles (AuNPs) was prepared by electrolysis method Au thin film which deposited on a glass substrate drop-casting technique structural, optical and topographic characteristic of were examined UV-VIS absorption, TEM electron microscopy, AFM atomic XRD diffraction. Antibacterial activity has been investigated against many pathogenic bacteria, including Escherichia coli, Staphylococcus aureus, bacillus Pseudomonas aeruginosa using well-spread method, the...

Abstract Because of its medical and biological uses, green nanoparticle production has gotten a lot attention. Bismuth oxide nanoparticles (Bi 2 O 3 NP) were synthesized using aqueous extract from cocoa plants in this study, the result was examined an ultraviolet-visible, spectro-photometer, Fourier transform infrared, X-ray diffraction, atomic force microscopy, The samples’ antibacterial activity tested against variety microorganisms.
