This research investigates the structural, morphological, and optical properties of Cadmium Selenide (CdSe) thin films deposited via Chemical Bath Deposition (CBD) Technique, focusing on impact Iron (Fe) doping. Using Chloride (CdCl
Zinc Oxide (ZnO) nanoparticles (NPs) have been synthesized by a simple chemical precipitation method. The effect of monoethanolamine (MEA) content in different solvents on ZnO NPs synthesis and their structural properties has investigated. using isopropanol (IPA) with 15 ml MEA as stabilizer under the most favorable conditions (deposition time, td = 120 min, temperature 60 °C) showed good properties. Synthesized exhibited beneficial after annealing. hexagonal wurtzite crystal structure was...
A series of multiferroic composites, (1-x)Ba0.6(Ca1/2Sr1/2)0.4Ti0.5Fe0.5O3+(x)Ni0.4Zn0.45 Cu0.15Fe1.9Eu0.1O4 ((1-x)BCSTFO+(x)NZCFEO) where x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 1.0 have been synthesized by standard double sintering ceramic method sintered for 3 hours at 1200°C in air. The X-ray diffraction patterns reveal that the multiferroics and parent samples crystallize simple cubic structure with a slightly distored lattice parameter. bulk density increase increasing ferrite content....
The structural properties of CBD deposited CdS thin films have been studied by varying the processing parameters and Cd/S ratio starting Precursors in order to better understand growth conditions. A film was prepared on glass substrate method from a bath containing Thiourea Ammonium hydroxide. analysis performed X-ray Diffraction (XRD). cubic phase with small nano crystalline grains. at 60°C for 2 hours. After sintering 300°C 1 hour color changed like dark yellowish thickness obtained 100...
Cadmium Sulfide (CdS) nano particles are synthesized by chemical precipitation method. Chloride and Thiourea used as the precursor materials. Ammonia water & distilled solvent. The samples annealed at 100°C, 300°C 500°C for 1 hour. Transmission electron microscopy (TEM), Energy–dispersive X-ray spectroscopy (EDAX), diffraction pattern (XRD) to study morphologies, distribution, crystallinity of CdS nanoparticles calculate values their sizes. results indicate that formed with Hexagonal...
Zinc Sulphide is one of most studied semiconductor with wide band gap (3.5–3.9 eV) versatile material due to its physical and chemical properties. ZnS a non-toxic suitable candidate be buffer layer for heterojunction solar cells. In this study, (ZnS) thin films were deposited by bath deposition technique using Acetate Dihydrate [Zn (CH3COO)2. 2H2O] Thiourea [CH4N2S]. The samples characterized UV-Vis NIR Spectroscopy, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy...
