Abstract :
The spectral dependences of optical absorption in the wavelength range 450...1100 nm and temperature range 23...70degC for the bismuth silicate crystal are considered. To describe the experimental dependencies of the impurity absorption the model of photo-excitation of electrons from deep levels to conduction band was used.
