“…Among them, photocatalysts based on CdS nanoparticles are of huge interest of scientists due to their wide bandgap energy (2.42 eV) [7] and reusability in photocatalytic processes [8]. In addition to photocatalysis, cadmium sulfide nanoparticles can be used in various fields of industries such as medicine [9], hydrogen production [10], photovoltaic devices [11], optoelectronics [12], diodes [13], gas sensors [14], etc. For example, in medicine, CdS nanoparticles reveal antibacterial [15], antimicrobial [16], and antifungal [17] activities against micro-organisms.…”

CdS nanoparticles were successfully synthesized using cadmium acetate and sodium sulfide as Cd and S precursors, respectively. The effect of using sodium thiosulfate as an additional sulfur precursor was also investigated (combined milling). The samples were characterized by XRD, Raman spectroscopy, XPS, UV-Vis spectroscopy, PL spectroscopy, DLS, and TEM. Photocatalytic activities of both CdS samples were compared. The photocatalytic activity of CdS, which is produced by combined milling, was superior to that of CdS, and was obtained by an acetate route in the degradation of Orange II under visible light irradiation. Better results for CdS prepared using a combined approach were also evidenced in photocatalytic experiments on hydrogen generation. The antibacterial potential of mechanochemically prepared CdS nanocrystals was also tested on reference strains of E. coli and S. aureus. Susceptibility tests included a 24-h toxicity test, a disk diffusion assay, and respiration monitoring. Bacterial growth was not completely inhibited by the presence of neither nanomaterial in the growth environment. However, the experiments have confirmed that the nanoparticles have some capability to inhibit bacterial growth during the logarithmic growth phase, with a more substantial effect coming from CdS nanoparticles prepared in the absence of sodium thiosulfate. The present research demonstrated the solvent-free, facile, and sustainable character of mechanochemical synthesis to produce semiconductor nanocrystals with multidisciplinary application.

“…Moh Husham et al 4 reported a responsivity of 0.24 A W −1 in nanocrystalline self-powered CdS photodetectors. Reports on the detection of specific wavelengths are available, as in the literature, 5 where M. S. Waldiya et al have reported a responsivity of 0.3815 A W −1 at 420 nm. Major drawbacks in CdS photodetectors are low efficiency and optical signal to noise ratio.…”

“…4. The intense sharp peak observed at around 300 cm −1 and less intense peak at 600 cm −1 is ascribed to the CdS fundamental longitudinal optical mode phonon (1LO) and its overtone (2LO), respectively [30]. There was no peak observed for SiO 2 in SiO 2 /CdS composites, although SiO 2 gave most noticeable bands at 436, 716, 1265, 1392, 1665, 1704 and 1760 cm -1 [31], this can be caused by amorphous nature of SiO 2 and also very less intense bands only observed for pure SiO 2 [31].…”
