Abstract: The Bi2O3-rich glass sample of the following composition 0.005•Gd2O •0.995 (0.875Bi2O30.125GeO2) was prepared by rapid cooling of the melts. The polycrystalline sample was obtained after 24 hours heat treatment of the glass sample. Glass and polycrystalline samples were characterized by DTA, X-ray, infrared (IR) and Raman spectroscopies. The developed crystalline phase formed after the heat treatment applied was identified as being Bi12GeO20. Structural model for the investigated glass sample is suggested on the basis of IR and Raman spectroscopic investigations on its crystalline counter part. | |||||||
