“…CdO is an n-type semiconductor which possesses direct and indirect optical band gaps of 2.5 eV and 1.98 eV, respectively [17]. Additionally, CdO deposited on porous silicon demonstrates an outstanding optical and electrical performance [18]. CdO has been widely applied in broad-based optoelectronic applications such as sensors, transparent electrodes, photo transistors, and solar cells [19][20][21][22].…”

In this article, cadmium oxide (CdO) was deposited using pulsed laser deposition approach on porous silicon (Si) wafer for visible light photodetector application, through which a series of devices were proposed as a function of the deposition energy. The microstructural as well as optical characteristics of the prepared film/s were demonstrated, respectively, using x-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and ultraviolet visible light spectroscopy (UV-Vis) analysis. In details, the UV-Vis analysis revealed the occurrence of optical band gaps within the range of 2.38 -2.42 eV, while an average nanoparticle diameter was found to be 45 nm using FE-SEM technique. This in turn demonstrated a sound relation with the photoresponsive behavior of the attained photodetectors. A photoresponsivity and specific detectivity of 1.9 μA/mW and 1.21×10^9 Jones were attained using 700 mJ laser energy. In the meanwhile, the estimated response/recover time of the addressed laser energy was found to be 300 sec. and 340 sec., respectively. The photo-responsive characteristics of the fabricated devices were found to be in positive linear correlation with the applied laser energy.

We study the impact of (MnO2–ZrO2) nanoparticles on optical properties of (PVA) polymer. Several samples were produced with different weight ratios of (MnO2–ZrO2) nanoparticles. To prepare the selected samples, the casting method is used. To record the absorption spectrum, wavelengths of 200–1100 nm are applied. We have determined the absorption coefficient, energy gap for indirect transitions (forbidden and allowed), optical constants (such as the dielectric constant with its imaginary and real parts, refractive index, and attenuation coefficient), and optical conductivity. The results indicate that there is a proportional relationship between the optical constants and the concentration of (MnO2–ZrO2) nanoparticles, which means that an increase of the concentration of (MnO2–ZrO2) nanoparticles leads to an increase of the optical constants, while the transmission decreases. Additionally, the optical energy gap decreases from 4.83 eV to 3.4 eV and from 4.65 eV to 3.28 eV with increasing the concentration of (MnO2–ZrO2) nanoparticles for allowed and forbidden indirect transitions, respectively. These results can be considered as key ones for the use of (PVA-MnO2–ZrO2) nanocomposites in various fields such as optoelectronics and photonics.
