| dc.description.abstract | In this work, new glassy compositions (As₄₅S₁₅Se₄₀)₁₋ₓSnₓ with x = 0 – 0.10 were synthesized, and thin films were obtained by thermal evaporation in vacuum. Structural and compositional characterization was performed by SEM, EDS, XRD and UV-VIS spectroscopy. The results revealed the amorphous and homogeneous nature of the samples, as well as a high optical transmission in the range of 0.4–0.9 μm, with an absorption edge between 1.96–2.06 eV. A significant photoinduced effect was observed upon irradiation with violet light, manifested by a shift of the absorption edge towards the IR. The materials show potential for applications in optoelectronics, holographic memory and IR waveguides. | en |
