“…However, (Ag₂O) silver oxide is the dominant one at (200) diffraction plane. The Significant improvement in the crystalline composition of the film at (1h) interaction time can be Identifiable, it can be found a similar presented results in other presented works [34][35][36]. The parameters of the crystal structural that defined of the structure values of the films deposited were estimated by make used the X-ray diffraction results by using the presented following mathematical expressions [37][38][39]: In table (1) the obtained value of structural constant could be shown, the average grain sizes found to be constant.…”

Chemical bath deposition method was employed for the deposition of smooth quantum size Ag2O nanostructure thin film on glass substrate at three different chemical interaction times. The structural properties shows the demonstration of Ag2O cubic structure at (002) diffraction plane. Optical properties reflect the dependence of energy gab on the interaction time with moderate band gab energy of about 2.25eV.Other physical properties such as SEM, AFM, was also investigated.

“…The XRD pattern shown in figure 3 informs the formation of phase pure tetragonal rutile and anatase, where 'A' and 'R' indicate anatase-phase crystals and rutile-phase crystals, respectively [18], as seen in the figure, for the energies 500, 600, 700, 800, 900, and 1000 mJ keeping this order the peaks for plane A(101) were located at 2θ = 24.8, 24.4, and not shown for the higher energies. For plane R( 110 The crystallite size (D) of all anatase and rutile peaks was calculated by using the Scherrer equation [19][20][21]…”

Because of its distinctive optical and electrical characteristics, titanium dioxide (TiO2) thin films are one of the significant and promising semiconductor materials for environmental and energy applications. The effect of the laser pulse energy of Nd:YAG on the properties of TiO2 thin film grown on silicon and quartz substrates using the laser pulse deposition technique by the crystal structure, surface area, crystalline structure, average particle size, and porosity were summarised. The nano-thin film with the optimum condition has been prepared with a pulse laser energy of 900 mJ. The optical properties have been investigated using UV–vis spectrophotometer, morphological properties have been studied using atomic force microscopy and field emission scanning electron microscopy, and structural properties have been examined using x-ray diffractometer and Raman spectrometer. The tests and measurements have shown a crystalline structure, and the distribution of the grains was regular in the film. Raman spectroscopy showed two diffraction peaks corresponding to anatase Eg and rutile Eg. This observation is typically used in dye-sensitised solar cells, separation sensor devices, and more.

“…Titania is a unique material given its versatile properties and is used for a wide variety of applications due to these properties, such as high photochemical corrosive resistance, nontoxicity, strong oxidizing power, high dielectric constant, transparency, high refractive index, resistance to chemical and physical impacts, and cost-effectiveness [4][5][6][7][8]. Due to these unique properties, it has great potential in different applications, such as electrical insulation, optical waveguides, anti-reflection coatings, capacitors or gates in microelectronic devices, bio, and gas sensors, and photovoltaic solar cells [9][10][11][12][13][14][15][16].…”

In this study, a Q-switched Nd:YAG laser with specific parameters, including a pulse repetition rate of 6 Hz, a pulse duration of 10 nm, a wavelength of 532 nm, and a laser fluence of 237.47 J cm−12, was employed to fabricate highly crystalline TiO2 nano-films. These nano-films exhibited a narrow energy band gap of 3.24 eV and showcased favorable surface morphology, characterized by a roughness of 2.38 nm. A solar cell device was produced by creating porous silicon (PSi) and applying titanium dioxide films onto the PSi, achieving a notable conversion efficiency of 8.733%. To investigate the impact of different parameters on the resulting TiO2 nano-films, a range of laser fluences (ranging from 131.93 to 263.85 J cm−12) and three distinct laser wavelengths (1064 nm, 532 nm, and 355 nm) were employed during the pulsed laser deposition (PLD) process. These experiments aimed to grow TiO2 films on both quartz and silicon (Si) substrates.
