“…After the incorporation of Ag NPs into WO 3 NPs, the absorption band edge of bare WO 3 is redshifted (toward a longer wavelength). The presence of both peaks provided evidence for the creation of the Ag–WO 3 core shell NPs 103 – 105 . This result gives a clear indication of the effect of Ag nanoparticles due to the effect of SPR coming from Ag (core) nanoparticles.…”

In this study, silver-tungsten oxide core–shell nanoparticles (Ag–WO3 NPs) were synthesized by pulsed laser ablation in liquid employing a (1.06 µm) Q-switched Nd:YAG laser, at different Ag colloidal concentration environment (different core concentration). The produced Ag–WO3 core–shell NPs were subjected to characterization using UV–visible spectrophotometry, X-ray diffraction (XRD), transmission electron microscopy (TEM), energy-dispersive spectroscopy, electrical analysis, and photoluminescence PL. The UV–visible spectra exhibited distinct absorption peaks at around 200 and 405 nm, which attributed to the occurrence of surface Plasmon resonance of Ag NPs and WO3 NPs, respectively. The absorbance values of the Ag–WO3 core–shell NPs increased as the core concentrations rose, while the band gap decreased by 2.73–2.5 eV, The (PL) results exhibited prominent peaks with a central wavelength of 456, 458, 458, 464, and 466 nm. Additionally, the PL intensity of the Ag–WO3-NP samples increased proportionally with the concentration of the core. Furthermore, the redshift seen at the peak of the PL emission band may be attributed to the quantum confinement effect. EDX analysis can verify the creation process of the Ag–WO3 core–shell nanostructure. XRD analysis confirms the presence of Ag and WO3 (NPs). The TEM images provided a good visualization of the core-spherical shell structure of the Ag–WO3 core–shell NPs. The average size of the particles ranged from 30.5 to 89 (nm). The electrical characteristics showed an increase in electrical conductivity from (5.89 × 10−4) (Ω cm)−1 to (9.91 × 10−4) (Ω cm)−1, with a drop in average activation energy values of (0.155 eV) and (0.084 eV) at a concentration of 1.6 μg/mL of silver.

“…The photoluminescence (PL) spectra of synthesized GaN at various laser ablation energy are shown in figure 8. The energy of the incident photon ( = E hv) [42][43][44][45][46], as a function of the wavelength (λ) was calculated using equation (1) [47][48][49][50][51].…”

The pulsed laser ablation approach was used to synthesize gallium nitride (GaN) nanoparticles (NPs) at six distinct ablation energies. The nanoparticle was deposited on a quartz substrate using the drop cast technique. Two peaks of h-GaN nanostructures are detected in the XRD pattern, at 2θ = 34.64 and 37.98, reflected from the (002) and (100) planes, respectively. The hexagonal crystal nature of GaN is indicated by the morphological features, which is shown in the XRD pattern. The greatest laser power, 2000 mJ, shows a modest emission peaking at 3.34 eV, according to photoluminescence (PL) spectra. At 1400 mJ, the highest emission peak was 3.83 eV. The pulsed laser is used in this study to create nanoparticles with various characteristics.

The deposition of copper oxide utilizing a pulsed laser deposition technique employing a reactive pulsed laser as a deposition technique is the subject of this study. The wavelength of the pulsed lase used are 1064 nm, the pulse duration is 10 ns, the laser energy of 1000 mj with different substrate temperatures (200, 3300, and 400 oC). The influence of the substrate tampering on the morphological, structural, Photolumencence, and the electrical, and attributes of the fabricated solar cell was recorded and studied using a high purity cupper target and deposited on porous silicon substrates. When compared to a crystalline silicon surface, the results of AFM show a higher possibility of better absorption and hence lower reflection. The presented results revealed the properties of the fabricated solar cell as well as a noticeable improvement in the solar cell's efficiency, whether copper deposition was used or not. The deposited films at 1064 nm were monoclinic structures with a preference for the (111) direction, according to X-ray diffraction (XRD) examination. SEM were used to study the production of nanostructures on the substrate's surface, which led to the formation of small-sized and nanostructured films.
