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

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.
