摘要：
The absorption and transmission spectra of Bi12MO20 (M = Ge, Si, Ti) sillenite crystals were studied in the range 300-900 nm. Doping and vacuum annealing were found to have a significant effect on the transmission spectra of the crystals both near the fundamental absorption edge and in the long-wavelength region. The spectral dependences of the photocurrent through Bi12GeO20, Bi12SiO20, and Bi12TiO20 are also discussed.
