✦ Synopsis

The galvanoluminescent brightness on filling of porous films obtained in H,SO, solution is studied. It is found that the matrix of the porous film which is filled up contributes to the light emission. It is also found that the light yield increases with growing thickness of the films on completely filled up pores and decreases on lilm thickness growing when the pores are very deep. Thus it is concluded that the light emission is only due to the barrier part of the porous f&n while the overlying porous-part absorbs some of the light. The galvanoluminescent brightness is also strongly affected by the type of the filling electrolyte US&.
