“…Similar to most other biopolymers, CA is semi-crystalline yet largely amorphous. The diffraction peaks around 10° and 20°, corresponding to the (101) and (020) planes, respectively, confirm the semi-crystalline nature of CA [ 22 ]. When the CdSe/CA ratio increased, the intensity of the CdSe peaks increased.…”

Solar thermal techniques provide a promising method for the direct conversion of solar energy to thermal energy for applications, such as water desalination. To effectively realize the optimal potential of solar thermal conversion, it is desirable to construct an assembly with localized heating. Specifically, photoactive semiconducting nanoparticles, when utilized as independent light absorbers, have successfully demonstrated the ability to increase solar vapor efficiency. Additionally, bio-based fibers have shown low thermal conductive photocorrosion. In this work, cellulose acetate (CA) fibers were loaded with cadmium selenide (CdSe) nanoparticles to be employed for solar thermal conversion and then subsequently evaluated for both their resulting morphology and conversion potential and efficiency. Electrospinning was employed to fabricate the CdSe-loaded CA fibers by adjusting the CA/CdSe ratio for increased solar conversion efficiency. The microstructural and chemical composition of the CdSe-loaded CA fibers were characterized. Additionally, the optical sunlight absorption performance was evaluated, and it was demonstrated that the CdSe nanoparticles-loaded CA fibers have the potential to significantly improve solar energy absorption. The photothermal conversion under 1 sun (100 mW/cm2) demonstrated that the CdSe nanoparticles could increase the temperature up to 43 °C. The CdSe-loaded CA fibers were shown as a feasible and promising hybrid material for achieving efficient solar thermal conversion.

“…Semiconductor nanoparticles (SCNPs) films made of II-VI compounds have distinct properties that make them suited to several devices and applications [2]. Tin dioxide (SnO 2 ), titanium-dioxide (TiO 2 ), cadmium-sulphide (CdS), cadmium-tellurium (CdTe), cadmium-selenide (CdSe), zinc selenide (ZnSe), zinc-oxide (ZnO), and zinc tellurium (ZnTe) are all well-known SCNPs and well-studied in detail [3][4][5][6][7][8][9][10]. Among the SCNPs, ZnS is one in particular that has been widely used for a variety of applications.…”

The pulsed-laser deposition (PLD) method was used to deposit undoped zinc sulphide (ZnS) and Al-doped zinc sulphide (AZS) films on glass substrates (GSs). The aluminum content in the ZnS films varied from 0% to 8%. The film morphology was studied using atomic force microscopy (AFM). The films were optically characterized using an Ultraviolet-Visible-near-infrared (UV-VIS-NIR) spectrophotometer with photon wavelengths ranging from 300 to 600nm. The average roughness (Sa), root-mean square (RMS) roughness (Sq), surface skewness (Ssk), and surface kurtosis (Suk) parameters of the samples were determined using the AFM method. The samples' AFM grain sizes were found to be 4.89 nm, 5.65 nm, and 12 nm, respectively. The doped ZnS thin film's surface roughness was found to be greater than the undoped ZnS thin film's. The samples showed a high transmittance across the whole visible spectrum, according to the UV data. The film optical refractive-index (n) and the extinction-coefficient (k) was computed using UV-VIS spectroscopy data. The techniques used in these investigations have been described and explained in detail. Good agreement was found when comparing results from this work against previously published data.
