“…The result shown in Fig.1 is consistent with that reported by Q Q Liu et al [17]. They studied the dependence of film growth rate as a function of ammonia concentration from 0.5 M to 1.0 M and found that the film growth rate was peaked at 1.5 M of concentration of ammonia.…”

“…It starts from an aqueous solution of salts of the elements of the compound to be obtained. It requires that the compound to deposit is relatively insoluble and chemically stable in the solution to give a simple precipitation in an ionic reaction 20 . The method of obtaining of CdS doped with rare earth was the chemical bath deposition in its modality of immersion, in which a cryo-thermostat of circulation Polyscience with temperature controller of -40 to 200°C was used.…”

Rare earths (Europium, cerium)-doped CdS nanofilms are prepared using the growth technique chemical bath deposition (CBD) at the reservoir temperature of 70±2°C varying the synthesis time in a wide range. For the rare earths doped CdS nanofilms the synthesis time was ranged from 80 to 135 min. The rare earths molar concentration was in the range 0.0≤x≤3.47, which was determined by energy dispersive X-ray spectroscopy (EDS). The X-ray diffraction (XRD) analysis reveals that CdS nanofilms showed the zinc blende (ZB) crystalline phase. The nanocrystal size was ranged from 2.67 to 2.35 nm for the CdS and 1.84-2.33 nm for rare earth-doped CdS that were determined by the Debye-Scherrer equation from ZB (111) direction and it was confirmed by transmission electron microscopy (TEM). The doped CdS exhibits a direct band gap that diminishes with the increase of the synthesis time, from 2.50 to 2.42 eV, which was obtained by transmittance. The room-temperature photoluminescence of CdS presents the band-to-band transition at 431 nm, which is associated with quantum confinement because the grain size is less than its Bohr exciton radius and a dominant band at 523 nm, which is called the optical signature of interstitial oxygen. Eu 3+ -doped CdS photoluminescence shows the dominant radiative peak at 576 nm that is associated to the intra-4f radiative transition of Eu 3+ ions, which corresponds to the magnetic dipole transition, (). For the Ce 3+-doped CdS the dominant radiative transitions are clearly redshifted. Additionally, other radiative peaks associated at structural defects are observed. The passivation of the CdS by rare earths was approximately of two orders of magnitude obtaining better results with cerium.

“…The CdS is a suitable n-type material, which can be fabricated by a variety of fabrication techniques like sol gel technique [4], close spaced sublimation (CSS), chemical bath deposition (CBD), thermal evaporation, chemical vapor deposition, molecular beam epitaxy and spray pyrolysis. Each and every deposition process provides different optical, structural, electrical and morphological properties [5][6][7][8][9][10]. First solar company has reported CdS deposited by high rate vapor transport deposition (HRVTD).…”

Abstract. Thin films of Cadmium Sulfide (CdS) are deposited on microscope glass slides by two techniques, chemical bath deposition (CBD) and close spaced sublimation (CSS). Cadmium Sulfide thin films fabricated by both procedures are characterized by spectrophotometer, scanning electron microscopy (SEM) and X-ray diffraction (XRD). Optical analysis of CdS thin films shows changes in transmittance, refractive Index and energy band gap by using two different techniques. XRD and SEM results show CdS thin film samples with better crystalline structure for close spaced sublimation technique and grain size is also found different for these two methods. CdS thin films fabricated by any of these two methods are good window layers with small thickness and suitable for CdTe/CdS/ITO based solar cells.
