Effect of composition on optical constants of Pb: GeSbTechalcogenide thin films
Kumar, J.; Kumar, P.; Suri, N.; Ahmad, M.; Thangaraj, R.; Sathiaraj, T.S. (2008)Optical properties of Pb doped ternary Ge-Sb-Te chalcognide films prepared by thermal evaporation have been studied in the visible and near-infrared spectral regions. The straightforward analysis proposed by Swanepoel has ... -
Optical properties of amorphous Sb2Se3:Sn films
Kumar, P.; Sathiaraj, T.S.; Thangaraj, R. (Taylor & Francis, 2010)The measurements and analysis of optical transmission and far-infrared (IR) reflectivity spectra of thermally evaporated Sb2Se3:Sn films are reported. The refractive index and film thickness have been determined from ... -
Structural, optical and fluorescence properties of wet chemically synthesized ZnO:Pd2+ nanocrystals
Kaur, J.; Kumar, P.; Sathiaraj, T.S.; Thangaraj, R. (SpringerOpen, http://www.inl-journal.com/, 2013)This paper presents the structural, optical and photoluminescence properties of wet chemically synthesized ZnO: Pd2+ colloidal nanocrystals characterised by X-ray diffraction, scanning electron microscopy/energy-dispersive ... -
Thermal analysis and annealing temperature dependence of electrical properties in Sn10Sb20Se70 glassy semiconductor
Kumar, P.; Thangaraj, R.; Sathiaraj, T.S. (Springer Netherlands, 2008)The melt-quenched Sn10Sb20Se70 sample in the bulk form was used to prepare films on well-cleaned glass substrates by thermal evaporation method. The activation energy for glass transition (apparent) and crystallization has ...
