ZnS/glass Thinlayer in high vacuum condition and $40$ degree‎ ‎Deposition angle has been produced by resistance evaporated method ‎with $28$ nm thickness‎. ‎cabin deposition temperature ZnS layer was‎ ‎about $50C$ and substrates were kept at room temperature‎. ‎The Atomic ‎Force Microscopy (AFM) and XRD analyses are perfectly accomplished‎ ‎for this layer.‎‎‎

A semiconducting water-soluble core-shell quantum dots (QDs) system capped with thiolated ligand was used in this study for the sensitive detection of glucose in aqueous samples. The QDs selected are of CdSe-coated ZnS and were prepared in house based on a hot injection technique. The formation of ZnS shell at the outer surface of CdSe core was made via a specific process namely, SILAR (success...

in this scientific research zns nanoparticle was synthesized via precipitation method. two samples were synthesized by this method. the nanoparticle was characterized by xrd techniques, and the size and kind of crystallinity were identified by x-ray diffraction pattern as well. the size measurement has been done by using scherrer's equation. the average sizes of nanoparticles in two sample...

InP quantum dots (QDs) are promising down-conversion phosphors for white light LEDs. However, the mainstream QDs synthesis uses expensive phosphorus source. Here, economic, in situ-generated PH3 is used to synthesize and a two-step coating of ZnS shells developed prepare highly luminescent InP/ZnS/ZnS QDs. The show photoluminescence yield as high 78.5%. emission can be tuned by adjusting halide...

High-density and well-aligned ZnO-ZnS core-shell nanocone arrays were synthesized on fluorine-doped tin oxide glass substrate using a facile and cost-effective two-step approach. In this synthetic process, the ZnO nanocones act as the template and provide Zn2+ ions for the ZnS shell formation. The photoluminescence spectrum indicates remarkably enhanced luminescence intensity and a small redshi...

Luminescent solar concentrator (LSC) incorporated with quantum dots (QDs) have been widely regarded as one of the most important development trends of cost-effective solar energy. In this study, for the first time we report a new QDs-LSC integrated with heavy metal free CuInS2/ZnS core/shell QDs with large Stokes shift and high optical efficiency. The as-prepared CuInS2/ZnS QDs possess advantag...

We have investigated the chemical state of In(Zn)P/ZnS core/shell nanocrystals (NCs) for color conversion applications using hard X-ray absorption spectroscopy (XAS) and photoluminescence excitation (PLE). Analyses of the edge energies as well as the X-ray absorption fine structure (XAFS) reveal that the Zn(2+) ions from ZnS remain in the shell while the S(2-) ions penetrate into the core at an...

The thermal stability of ZnS nanowires grown in a Au/Pd-mediated vapor-liquid-solid manner was studied by using an X-ray diffractrometer equipped with an in-situ heating system. Using an in-situ heating X-ray system, we monitored the structural degradation of ZnS nanowires in the temperature range from 25 ◦C to 900 ◦C. From the X-ray diffraction data recorded from 25 ◦C to 900 ◦C, the as-synthe...
