An Analysis of Structural and Optical Properties Undoped ZnS and Doped (with Mn, Ni) ZnS Nano Particles

Impact of pH value on the Structural and Optical Studies of ZnS & ZnS-Ni Nano Materials

The behavior of doped and undoped nano-particles find a great deal of application in opto-electronic and semiconductor devices, so ZnS nano-crystals were grown into poly-vinyl alcohol matrix by chemical route at different wt percentage. Optical properties of both undoped and doped with ZnS nano-crystalline compounds were studied. The nano structure was characterized with the help of X-ray diffr...

Optical and Magnetic Properties of Mn-Incorporated ZnS Nanorods

Structural and Optical Properties of Chemically Synthesized ZnS Nanoparticals

Different samples of ZnS nanoparticals were synthesized by chemical co-precipitation method at room temperature using zincsulphate as zinc source and sodium sulphide as sulphur source. Structural properties of synthesized ZnS nanoparticles were studied by X-ray diffraction pattern (XRD) while optical properties were examined by UV-Visible absorption spectroscopy. XRD pattern showed the as synth...

Optical and photocatalytic properties Undoped and Mn-doped ZnO nanoparticles synthesized by hydrothermal method: Effect of annealing temperature

Undoped and Mn-doped ZnO nanoparticles were successfully prepared by the hydrothermal method with different annealing temperature conditions. Structural, chemical and optical properties of the samples were studied by X-ray diffraction (XRD), Field Emission scanning electron microscopy (FESEM), UV-Vis spectrophotometry and Fourier transform infrared (FT-IR) spectroscopy. The phase purity was con...

Mn-doped ZnS nanoparticles as efficient low-voltage cathodoluminescent phosphors

We have synthesized nanoparticles of ZnS doped with Mn for potential use as cathodoluminescent phosphors in field-emission displays ~FEDs!. We show that the cathodoluminescent efficiency of particles <100 nm in diameter is within 40% of that of a commercial ~micron-sized! phosphor when the electron-beam energy ranges between 500 and 3500 eV. The nanoparticles exhibit less current saturation tha...
