【摘要】 本文研究了渗TiO₂高硅氧玻璃的结构与光吸收性。实验结果表明玻璃的光吸收决定于玻璃中的锐钛矿微晶,微晶增大、减小可使玻璃的光吸收限向长、短波方向移动。直径约80A的锐钛矿微晶就能显示出与大块晶体一样的光吸收限。更多还原

【Abstract】 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 A shows the same absorption edge as that of bulk crystal.更多还原
