Bismuth and lead doped silicon and germanium-oxide glasses are used, among others, for electron continous-dynode, electron (and photon) amplifiers. To make them conducting, reduction procedures in hydrogen atmosphere are applied. The depth of the reduced layer must be thoroughly chosen, in order to assure a high secondary-electrons yield, and to assure a low surface conductivity, on the other hand.
