Abstract: 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 SiO$_2$ and H$_x$SiO$_y$ 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.
