摘要：

Complex refractive indices of thermally evaporated SbxSe100-x thin films, both amorphous (as deposited) and crystallized after thermal treatment are determined in the spectral range 400-1000 nm. The results are used to simulate the optical characteristics (reflection, absorption and phase difference) of multilayer stack configurations including two protective dielectric layers, a reflective layer and SbxSe100-x thin films as a phase-change recording layer. Optimal multilayer stack configurations as a function of the recording layer composition are determined. The applicability of SbxSe100-x thin films as recording materials for CD-RW and DVD-RW optical disks at lambda = 640 and 780 nm is discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
