摘要:
The sol-gel method is used to obtain thin films with the composition Bi12SiO20. The characteristic features of the technology for obtaining the films are presented. Diffractometry confirmed that the films possess gamma-Bi2O3-type structure. The transmission spectra of the films were investigated. The spectral dependence of the absorption coefficient of the films matches well with the spectra determined using bulk Bi12SiO20 crystals. (C) 1999 American Institute of Physics.
