Abstract
In my recent work, investigating the influence of addition of cadmium (Cd) with decreasing atomic wt. % of Selenium (Se) at constant atomic wt. % of Tellurium (Te) on the optical studies of the Se90-xTe10Cdx (x = 0, 10, 20 at. %) chalcogenide alloys. Spectral dependence of the absorption spectra recorded in the range of 200 1800 nm for as-prepared and thermally annealed samples in normal wavelength scanning mode is shown by UV/VIS/NIR spectroscopy. Optical band gap (Eg) of the as-prepared sample increases and thermally annealed sample decreases with increasing photon energy. Absorption coefficient and absorption constant of the as-prepared and annealed samples S1, S2, S3 decrease with increasing Cd% in the synthesized materials.
