Cu doped ZnS Nanoparticles in powder form were prepared by wet chemical route method by using thioglycerol as a capping agent. The prepared powder was characterized by using X-ray diffraction (XRD) analysis. The XRD studies indicated that most of the samples are having cubic phase. The absorption spectra, and photoluminescence behaviour of bulk ZnS, nano ZnS and Cu doped ZnS have been studied. ...

Doped ZnS quantum dots (QDs) have a longer dopant emission lifetime and potentially lower cytotoxicity compared to other doped QDs. The liver is the key organ for clearance and detoxification of xenobiotics by phagocytosis and metabolism. The present study was designed to synthesize and evaluate the hepatotoxicity of Mn-doped ZnS QDs and their polyethylene glycol-coated counterparts (1 mg/kg an...

Pure and copper doped ZnS nanoparticles in powder form were prepared by wet chemical route method by using thioglycerol as a capping agent. The XRD studies indicate that the samples are cubic in nature. The thermoluminescence (TL) behavior of pure and copper doped ZnS has been studied for fixed 10 min UV exposure time; TL glow curve shows a single peak at 165.1°C and 184.3°C temperature respect...

Pure and doped ZnS nanocrystalline phosphors were prepared at room temperature using a chemical synthesis method. Transmission electron microscopy observation shows that the size of the ZnS crystals is in the 2-3 nm range and SAED pattern confirms the cubic and crystalline nature of the observed samples, which are in agreement with X-Ray analysis. Interesting luminescence characteristics such a...

ultrasonic-assisted method was applied for preparation of cu+2-doped zns nanoparticles (mole fractions of cu+2 ions are 0.000, 0.015, 0.030 and 0.060) in water as a template-free and green method at 30 min. the prepared nanoparticles were investigated by powder x-ray diffraction (xrd), scanning electron microscopy (sem), energy dispersive x-ray (edx) and uv–vis diffuse reflectance spectra (drs)...

Reducing the oxidative capacity of holes (h(+)) in the valence band (VB) of ZnS is one of the most effective ways to prevent the photocatalyst from photocorrosion. In this work, ZnS doped only with nitrogen was prepared for the first time by nitriding ZnS powder in an NH3 atmosphere. We demonstrate theoretically and experimentally that the valence band maximum (VBM) rises obviously by N-doping ...

For the first time, we report the applications of Mn(2+)-doped ZnS@cysteine nanoparticles (NPs) as matrices for analysis of coccidiostats (lasalocid, monensin, salinomycin and narasin) and peptide mixtures (Met-enk, Leu-enk, HW6 and gramicidin) in surface-assisted laser desorption/ionization time-of-flight mass spectrometry (SALDI-TOF MS). The Mn(2+)-doped ZnS@cysteine NPs have been successfull...

Thin films of indium doped zinc sulfide (ZnS) for different indium (In) concentrations (x=0.0 - 0.8) were deposited onto glass substrate by spray pyrolysis method at 523K temperature. Aqueous solution of zinc acetate, indium chloride and thiorea were used to deposit the In-Zn-S film. The deposited thin films were characterized by Energy dispersive X-ray (EDX), Scanning electron microscopy (SEM)...

A new room-temperature phosphorescence (RTP) mercury ions sensor has been developed based on cetyltrimethylammonium bromide-capped Mn-doped ZnS quantum dots (CTAB/Mn-ZnS QDs) and label-free thymine (T)-rich aptamer. The formed T-Hg(2+)-T dsDNA can linearly quench the RTP of Mn-ZnS QDs through electron transfer and aggregation effect, and give a detection limit of 1.5 nM.

A general approach for the synthesis of manganese-doped II-VI and III-V nanowires based on metal nanocluster-catalyzed chemical vapor deposition has been developed. High-resolution transmission electron microscopy and energy-dispersive X-ray spectroscopy studies of Mn-doped CdS, ZnS, and GaN nanowires demonstrate that the nanowires are single-crystal structures and homogeneously doped with cont...
