   The optical edge and IR spectra absorption of a-Ge0,85Si0,15:H hydrogenerated amorphous films, obtained by the plasmochemical precipitation at different partial pressures of hydrogen (PН2), have been investigated. The amount of hydrogen (Р) in solid solution is determined. It has been revealed that the oscillator strengths depend on the hydrogen concentration; they decrease with the hydrogen effusion and increase with the increase of the hydrogen content (PН2) in the atmosphere of the obtained a-Ge0,85Si0,15:H films at partial pressures 0.6—3.0 mTorr.
