“…All these observed vibration modes are in good agreement with those reported for LiNbO 3 single crystal [95,96]. The changes in the peak width and intensity are attributed to changes in the stoichiometry of LiNbO 3 films [97,98]. As the laser fluence increases, the Raman peak intensity also increases.…”

The use of LiNbO3 nanoparticles in nonlinear applications is attractive and promising. The particle size and morphology of LiNbO3 are the key parameters affecting their application. In this study, spherical nanoparticles of lithium niobate were synthesised by nanosecond Nd:YAG laser ablation in water. The polycrystalline, rhombohedral structure of the synthesised LiNbO3 nanoparticles with x-ray diffraction experiments was verified. The bandgap energy of colloidal LiNbO3 nanoparticles varied between 4.25 and 4.9 eV based on the laser fluence, according to the optical characteristics. The photoluminescence (PL) reveals that the emission peaks are centered at 293, 300, 305, and 309 nm for samples prepared at 1.3, 1.6, 2.0, and 2.2 J cm−2/pulse, respectively. The transmission electron microscope investigation confirmed the formation of spherical nanoparticles with an average size ranging from 18 to 34 nm. Raman studies on nanoparticles synthesised at various laser fluences are being conducted.

“…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. As result the values of the structural Strain and the values of the density of structural dislocations show a very little variation with time.…”

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 direct energy gap was estimated for the relation (4), the direct band gap has been found to decline by increasing the doping percentage (3wt% and 5wt %) and increasing the band gap when doping increase at 7wt% due to the shift from Moss-Burstein [21][22][23][24][25].…”

In this research, investigated characterization of pure and Cobalt doped Tin dioxide SnO 2 :Co with 3, 5 and 7wt% fabricated using radio frequency magnetron sputtering method deposited on glass surfaces. The results showed that prepared SnO 2 :Co were nano films and poly crystalline in form with favored reflection permanently (110) plan, and the crystallite size decreases as the Co concentration increased 9-14 nm. The optical properties represented by the transmittance of perspicuous and cobalt transplantation SnO 2 layers were studied and results showed that highest transmittance obtained was 91% in the pure films and decreased to 78% as the Co concentration increased; the wavelength range was 300-900 nm due to be the increasing of the Co amount during the deposition, leading to a linear increase in mobility and carrier concentration, until a threshold of Co content was overcome and from that point onward the mobility began to decrease. Optical energy gaps of perspicuous and Co transplantation SnO 2 nano layers were determined and the energy gap was reduced from 3.50 eV of perspicuous nano layers to 3.29 eV for the highest transplantation concentration.
