The optically active defect centers of such types as E', two kinds of oxygen-deficiency and some kinds of oxygen-richness in silica play an important role in optical communication fiber and UV absorption. The researches on some oxygen-deficient defects and the metal ions doped or implanted semiconductor nanoparticles with fine luminescence properties have made it possible for silica to be used in the lighting field.
