heal.abstract Thin Ge30Sb10S60 films were prepared and changes of their optical properties, Raman and infrared spectra, induced by illumination and annealing have been studied. Bleaching and darkening of exposed films was observed, depending on the initial state of the film and conditions of light exposure or annealing. The changes of optical properties are assigned to the change of homopolar bond densities. The dispersion of the refractive index of the virgin, exposed and annealed films can be described using the Wemple-Di Domenico single-oscillator model. Changes of the single oscillator energy, E0, and dispersion energy, Ed, induced by illumination and annealing are discussed. © 1995 Elsevier Science B.V. All rights reserved. en
