OPTICAL ABSORPTION PROPERTY OF TiO2-DOPED VYCOR GLASS
渗TiO2高硅氧玻璃的光吸收性

The structure and optical absorption property of TiO2-doped Vycor glasses are studied. The experimental results indicate that the optical absorption of the glasses are determined by anatase microcrystals in the glasses. The absorption edge shifts to long (or short) wavelength with increasing (or decreasing) of the microcrystal size. Anatase microcrystal of diameter about 80 ? shows the same absorption edge as that of bulk crystal.
