“…[155] This was also observed for many other types of perovskite and classical II-VI NCs and their thin films. [156][157][158] Due to the rather large difference between the ionic radii of Mn 2+ (0.8 Å) and Pb 2+ (1.19 Å) cations, the possibility of phase separation is large, and therefore, only a small amount of Mn 2+ can be doped into the CsPbBr 3 perovskite crystal structure. However, Chen et al, showed that Mn 2+ ions successfully replaced Pb 2+ ions in CsPbCl 3 NCs@glass composite.…”

Metal halide perovskites with excellent optical and electronic properties have become a trending material in the current research. However, their limited stability under ambient conditions degrades quality and threatens their potential commercialization as optoelectronic devices. Various approaches are adopted to improve the stability of perovskite nanocrystals (PeNC) while maintaining their advantageous optical properties, particularly strong luminescence. Among different possible improvement strategies, encapsulation of PeNCs within the amorphous glass matrices of inorganic oxides has drawn widespread attention because it ensures high resistance against chemical corrosion and high temperature, thus enhancing their chemical, thermal, and mechanical stability with improved light‐emission characteristics. In this article, two types of materials, namely all‐inorganic metal halide PeNCs and amorphous oxide glasses are briefly introduced, and then the methods are reviewed to fabricate and improve the quality of PeNC@glass composites. These methods are classified into three universal categories: compositional modification, structural modification, and dual encapsulation. In the final part of this review paper, examples of applications of PeNCs@glass composites in light‐emitting devices and displays, data storage and anti‐counterfeiting, lasing, photodetectors and X‐ray detectors, photocatalysis, optical filters, solar concentrators, and batteries are provided.

“…Excitonic states may involve in the PL emission process through recombination of excited electrons in the conduction band and generated holes in the valence band. This recombination leads to an emission peak of CdS QDs [39]. Also, it had been demonstrated that the changes in fluorescence emission spectra of CdS nanostructures resulted from their different band-edge emission which determined by their shapes and sizes [40].…”

Presence of inorganic pollutants in water reservoirs is the treating factor for human health and environment. Semiconductor quantum dots (QDs) has been regarded as one of the most efficient nanoparticles for their enhanced photocatalytic activity. Medicinal plants are the safe sources to provide green template for biosynthesis of inorganic nanoparticles such as quantum dots. In order to determine the photocatalytic and biological application of cadmium sulfide quantum dots (CdS QDs), a biosynthesis approach was employed using saffron (Crocus sativus L.) stigma extract as the green reaction substrate. The biosynthesis process was evaluated at different pH condition to obtain the most efficient CdS QDs. Characterization of prepared CdS QDs were determined through UV-Vis and fluorescence spectroscopy, FTIR and TEM analysis. The obtained results showed well dsispersed and uniform QDs during green synthesis at the optimum condition. The absorption and electrical properties of green synthesized CdS QDs showed the lowest energy bandgap of 2.4 at pH 11. Photocatalytic activity of CdS QDs on Rhodamine B degradation showed 92% degradation after 80 min under UV light irradiation. The antibacterial and cell cytotoxicity of green synthesized CdS QDs were assayed by disk diffusion and MTT assays respectively. Obtained results showed significant antibacterial effect of CdS QDs against gram-positive and gram-negative bacteria including B. subtilis (90%) and E. coli (96%) respectively. Moreover, cytotoxicity of prepared CdS Qds through MTT assay indicated 79% apoptosis induction on MCF-7 breast cancer cells.

“…The doping of various transition metal ions can generate impurity levels in the band gap of nanomaterials, thus improving charge separation and recombination dynamics. For example, doping Mn-ions into semiconductor nanomaterials has been extensively studied to obtain high emission quantum yields and long emission lifetimes for energy storage [14]. The doping effect of Mn-ions is also desirable to improve the NLO properties.…”

Graphene has broad prospects for application in photonic devices. However, its zero-band gap limits its nonlinear optical (NLO) properties, and thus, its application. In this study, we synthesized reduced graphene oxide modified by Mn-doped semiconductor CdS nanoparticles (RGO/CdS:Mn) via a solvothermal method to study the development of NLO properties of graphene. The structures, morphologies and basic physical properties of RGO, CdS, RGO/CdS, and RGO/CdS:Mn were characterized. The third-order optical nonlinearities were tested by the Z-scan technique using a mode-locked Nd:YAG laser operating at 532 nm with a 30 ps pulse width. The results showed that the nonlinear susceptibility and saturation absorption of RGO/CdS:Mn were 15.3 and 26 times higher than those of RGO, respectively. The mechanism of the enhancement was analyzed based on the charge transfer between and within the components, and Mn doping produced trapping effect. The significantly improved optical nonlinearity of RGO/CdS:Mn lays a foundation for its applications in photonic devices.
