摘要：
Infrared (IR) transmission spectra in the range from 4000 to 400 cm(-1) have been measured at ambient temperature for the prepared, (Ge22Se14Te64)(100-x)I-x, glasses where x = 0, 4, 6, 8 and 10 at.%. The effects of both iodine content and the annealing of glasses at different temperatures on the transmittance and observed absorption peaks have been evaluated. Scanning electron microscope (SEM) micrographs were performed to insure the effect of annealing on the obtained IR transmission spectra. (C) 2012 Elsevier B.V. All rights reserved.
