Abstract

Quantum-size silicon enriched regions were formed in silica porous glasses obtained by three different technologies. Processing in the spark discharge and carbon reduction of silicon dioxide in the solid phase were performed for this purpose. All fabricated specimens have been investigated in relation to their electrical and photoluminescence (PL) properties. A pronounced increase of visible luminescence and single-type changes in the a.c. conductivity were registered in all cases.
