碘化亚铜微晶掺杂硼硅酸盐玻璃的制备及其电致二阶非线性光学效应

采用可分相的Ｎａ２－Ａｌ２Ｏ３－Ｂ２Ｏ３－ＳｉＯ２系为基础玻璃，以ＣｕＯ／ＳｎＯ、ＮａＩ为原料，分别引入Ｃｕ＾＋、Ｉ＾－，成功地制备出ＣｕＩ微晶掺杂硼硅酸盐玻璃。通过Ｘ射线粉末衍射（ＸＲＤ）和高分辨透射电镜（ＨＲＴＥＭ）分析观察到了玻璃中的晶相及其分布；由玻璃的室温透射光谱研究了玻璃的热处理条件下光吸收性的关系。首次报道了该半导体微昌掺杂玻璃中的电致二次谱波发生，并讨论了该效应的机理。

Preparation and Electroinduced Second Order Nonlinear Optical Properties of CuI Microcrystal Doped Borosilicate Glasses

By selecting phase-separable glass system Na₂O-Al₂O₃-B₂O₃-SiO₂ as the base glass and by introducing Cu⁺, I^- from the starting materials CuO/SnO and NaI respectively, CuI microcrystal doped borosilicate glasses have been prepared successfully. The microcrystal and its distribution in the glass medium are observed by means of X-ray diffraction and HRTEM. The effects of heating treatment on the optical absorption of glasses is studied through the room transmission spectra of glasses. The electroinduced second harmonic generation in the glasses is reported. The mechanism of this effect is also discussed.
