摘要：
It is experimentally demonstrated that the point electron-beam irradiation of a nanoporous silicate glass leads to the appearance of or significant increase in the UV-excited luminescence from the entire sample in the spectral intervals of 500–700 and 900–950 nm. The observed effect is related to (i) partial reduction of SiO2 and HxSiOy phases by electrons that spread via through pores in the glass and (ii) an increase in the number of Si-H and Si-OH bonds.
