“…It was clear that the nanostructures that were prepared at a temperature of 300 degrees Celsius are the most uniform and consistent and the most uniform distribution among the rest of the temperatures used and it did not cause agglomeration of the granules or cracks in the surface, but was an ideal growth of the granules [49][50][51]. The Capacitance-Volt (CV) measurements for the prepared copper Nano oxide at different substrate temperatures are shown in Figure 3.…”

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.

“…Despite the above, it has been found that there is a lot of unusual characteristics, for example, chemical instability and oxidation susceptibility [13,14]. While the AuNP has many of the properties nanometal colloids make them especially suitable for biological applications, namely: they are highly versatile in scale, shape, and surface chemistry, they are stable in a wide variety of environments, they are inert, non-toxic, and they have optical-electronic controllable properties [15,16]. In Au NWs synthesis, the control of size, shape, and surface functionality are very important issues.…”

In this work, gold nanoparticles have been synthesized using second harmonic generation ND-YAG laser ablation in Ethanol employing 532 nm and 1.064 nm wavelengths. Field emission scanning electron microscope (FESEM), Transmission electron microscopy (TEM)X-Ray diffraction (XRD), Atomic force microscopy (AFM), photoluminescence (PL) spectroscopy, and UV-Vis absorption were employed to examine the structural, chemical and optical properties of Au NPs. XRD results showed that all synthesized Au nanoparticles are crystalline in nature. the optical band gap upon ablation using the higher wavelength (1064 nm) was about (4.02 eV). While the value of the optical bandgap increases to reach a value of (4.22 eV) at the shorter wavelength (532 nm The FESEM results reveal the formation of smaller nano rode size at second-harmonic generation (SHG) wavelength was found to be about (30 nm at wavelength 532 nm and 44 nm at 1064nm). After that, Finite Element Analysis is used to simulate the photonic crystal fiber (PCF) as biosensors, depending on the surface Plasmon resonance (SPR) phenome-non using COMSOL Multiphasic program. The hollow core-photonic crystal fiber (HC-PCF) HC-800 was thus overfilled with (water). The confinement loss (CL) of the fundamental mode for the proposed PCF with and without the gold nanoparticles was calculated, we observe without gold NPs the CL at the water and Colon tissue about (1.08E+03, 5.46E+02) dB/m, while at use the deposited PCF with gold NPs the results ensured the decrease more than in the confinement loss at the water and Colon tissue about (1.01E+03, 3.16E+02) dB/m with a clear shift toward higher wavelengths, also when calculating the sensitivity, to increase HC-PCF bio-sensor performance by using wavelength interrogation and amplitude measurements, it found the bio-liquid (colon tissue) has the best electric field using the gold NWs layer in the biosensor equal to 68.8 V/m by comparison when without using the gold NWs layer which leads to high sensitivity.

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.
