Abstract

We have studied luminescence of silica porous glasses excited by the UV laser. Two wide peaks with maxima at about 540 and 740 nm were observed. They did not change after thermal treatment at 200-degrees-C andthus were not attributed to the capillar water. After the treatment in hexamethyl-disilazane the peak at 740 nm completely vanished. We argue that this peak is due to the water molecules, chemically bonded on the surface of voids and that visible luninescence is connected with silicon enriched regions (silicon clusters).
