摘要：

The optical constants (the refractive index n and the absorption index k) of Sb2Se3 thin films deposited at room temperature on quartz have been calculated in the wavelength range (5000-2000 nm) using a transmission spectrum. Both n and k were found to be practically independent on either time, up to 6 months, or the film thickness in the range of 102-760 nm. Beyond the absorption edge, the absorption is due to allowed indirect and direct transitions with energy gaps of 1.225 and 1.91 eV, respectively. The value of the optical gap depends on the annealing temperature. X-ray analysis showed that the prepared films at room temperature had amorphous structure while the films annealed at 200-degrees-C for 1 h were verified to be crystalline.
