用sol-gel法以正硅酸乙酯、乙醇和蒸馏水为原料,以盐酸为催化剂,包埋三联吡啶钌[Ru(bpy)3Cl2]制备催化 Belousov-Zhabotinsky (BZ)反应的非线性光催化薄膜,并利用紫外分光光度法测定了在薄膜中Ru(bpy)3Cl2的包埋量.通过投影图像的方法光激发BZ反应,在包埋Ru(bpy)3Cl2的薄膜上产生化学波图像.在薄膜中演化形成的图像具有相当高的图像清晰度.在图像的演化过程中,具有图像反转、边界增强、图像分割等图像处理能力,并可以通过改变BZ反应条件来调控增强某些图像处理能力.

Nonlinear optical membrane used for image processing was prepared using tetraethyl silicate (TEOS) by sol gel method under mild conditions. Ru(bpy)3Cl2 was immobilized in the sol-gel matrix and its amount was measured by UV absorbency. This light-excitable membrane containing Ru(bpy)3Cl2 as photocatalyst could catalyze Belousov-Zhabotinsky (BZ) reaction by illumination. Our results indicated that a fine-definition image processing could be auto-performed when projecting a picture on this medium. The imaging process possesses several image processing effects, such as boundary enhanced effect and image reversion, which could be enhanced by adjusting some conditions of BZ reaction or the time of projecting.

Key words: sol-gel method, Ru(bpy)3Cl2, Belousov-Zhabotinsky reaction, light-catalysis, image processing
