“…However, at the (200) diffraction plane, (Ag2O) silver oxide predominates. It is possible to identify an improvement significant in the composition of the crystalline for the Nano-film at an interaction period of (1800) mJ, and comparable results have been reported in previous publications [24][25][26]. The following mathematical formulas [27][28][29] were used to estimate the structural of the crystal parameters that specified the values of the structure for the deposited Nano-films using the X-ray diffraction results:…”

High purity, micro, and nano size Ag2O nanostructure films were deposited by pulsed laser deposition on the quartz substrates at different pulsed laser Energies. The Ag2O cubic structure is supported by structural and optical features, with the primary diffraction occurring from the (002) plane. The obtained band gap energy was around 2.25eV, and optical features indicate the temporal dependency of the energy gab.

“…There are different types found in nature or synthesized from different crystal forms of nano or micro-crystalline copper oxides, or as it can be called (tenorite oxide) or copper oxide (CuO), which have monoclinic structures of various phases, as well as the cuprite phase or the copper oxide phase (Cu2O) with its cube-shaped structure [1][2][3][4].…”

A single-step of pulsed laser deposition method was used to manufacture (Cu2O) cuprous oxide nanothin films on Silicone substrates at low growing temperature in this study. The effects of three parameters of pulsed laser energies (800-1200 mJ) was used to explored in order to maximize the structural and morphological quality. (XRD) X-ray diffraction, Scanning electron microscopy with field emission (FESEM), and Atomic force microscopy were used to evaluate the effects of laser pulsed energies on the characteristics of Cu2O nanofilms (FESEM). When compared to a crystalline silicon surface, the results of AFM show a higher possibility of better absorption and hence lower reflection.

“…Cuprous oxide (Cu 2 O) is a semiconducting, cubic crystal structure, inexpensive and low toxicity nature with relatively low direct band gap of about 2.0 2.6 eV [1,2]. Furthermore, it has superior photo electronic properties, abundantly available and simple preparation procedures [3,4]. Cu 2 O has a unique cuprites structure through a body-centered cubic packing of copper atoms with oxygen atoms occupying the tetrahedral sites [5,6].…”

A seed layer-assisted chemical bath deposition (SCBD) method at low temperature has been developed to growth uniform and high crystal quality cuprous oxide (Cu 2 O) nanoparticles on transparent conductive/glass substrates. These lms were grown on indium-doped tin oxide (ITO) as seed layer which deposited on glass substrates using magnetron sputtering-RF . The ITO seed annealing process by continuous beam (CW) of CO 2 laser was used prior to growing the Cu2O nanoparticles. In this study, controlled synthesis of Cu 2 O lms were investigated by controlling the growth temperature at 55, 60, 65, and 70 o C, respectively. The products of lms were characterized in detail by using eld emission scanning electron microscopy (FESEM), X-ray diffraction (XRD). Optical properties of this Cu 2 O nanoparticles were examined UV-Vis spectroscopy. The study suggests synthesis route for developing high quality Cu 2 O nanoparticles using SCBD method for optical and electronic applications.
