Mn-doped nanocrystalline ZnO particles have been successfully synthesized at low temperature (80 ̊C) by the coprecipitation method using zinc sulfatehepta hydrate and NaOH. The structural and magnetic properties have been characterized using X-ray diffraction (XRD), Energy dispersive x-ray, vibrating sample magnetometer and electron spin resonance. XRD measurements revealed that the sample posse...

The spectroscopic studies of transition metal complexes of iron. metal complexes, are characterized by XRD, FTIR, H NMR, Mössbauer and VSM (vibrating sample magnetometer) measurements, are reported in the present paper. The XRD analysis reveals the crystalline nature of all the compounds. Mössbauer study interprets paramagnetic nature of complexes at room temperature. VSM measurements also reve...

Rhombohedral Boron Nitride (r-BN) layers were grown on sapphire substrate in a hot-wall chemical vapor deposition reactor. Characterization of these layers is reported in details. Xray diffraction (XRD) is used as a routine characterization tool to investigate the crystalline quality of the films and the identification of the phases is revealed using detailed pole figure measurements. Transmiss...

This paper reports the detailed preparation process of Eu2+ activated long lasting Sr4Al14O25 nano sized phosphor by precipitation method. Scanning electron microscopy (SEM), simultaneous DSC–TG, X-ray diffraction (XRD), photo luminescent spectroscope (PLS) and thermal luminescent (TL) spectroscope were employed to characterize the phosphor. SrAl2O4:EuDy and Sr4Al14O25:EuDy phosphors in nano sc...

Sintered samples of monoclinic zirconia (α-ZrO2) have been irradiated at room temperature with 6.0-GeV Pb ions in the electronic slowing down regime. X-ray diffraction (XRD) and micro-Raman spectroscopy measurements showed unambiguously that a transition to the ‘metastable’ tetragonal phase (β-ZrO2) occurred at a fluence of 6.5x10 cm for a large electronic stopping power value (≈ 32.5 MeV μm). ...

Mn-doped ZnS nanorods synthesized by solvothermal method were successfully coated with ZnS shells of various thicknesses. The powder X-ray diffraction (XRD) measurements showed the ZnS:Mn nanorods were wurtzite structure with preferential orientation along c-axis. Transmission electron microscopy images (TEM) revealed that the ZnS shells formed from small particles, growing along a-axis orienta...
