Several new crystal-amorphous composites which exhibit high ionic conductivity, photochromism, etc. were prepared by using some sophosticated techniques like twin-roller quenching and the sol-gel method. The following results were obtained.1) Superionic composites composed of alpha-Agl crystal and Agl-Ag_2O-M_xO_y glass were prepared by twin-roller quenching of the Agl-Ag_2O-M_xO_y melts with high concentration of Agl. The FE-SEM observation indicated that fine particles of alpha-Agl with several ten nanometers in diameter were uniformly dispersed in the glass matrices.2) Photochromic composites composed of heteropolyacids/viologens and silica gels were prepared by the sol-gel method. The colored species formed by the reduction of heteropolyacids/viologens were stabilized in the course of sol-gel transformation.3) Proton-conductive composites composed of bronsted acids and silica gels were prepared by the gol-gel method. The conductivities of such composites were as high as 10^<-4>-10^<-1> Scm^<-1> at room temperature.3) Auramine 0 (Au0), one of the microviscosity proves, was doped in the silica sols and the emission behavior was monitored in the course of sol-gel transformation and aging and drying of the wet-gels. The microviscosity surround Au0 did not change at the gelation point and steeply increased in the drying process.

通过使用一些大约溶胶技术（如双旋转剂淬灭和Sol-gel方法）制备了几种新的晶体肉类复合材料，它们表现出高离子电导率，光致变色等。 1）由α-AGL晶体和AGL-AG_2O-M_XO_Y玻璃组成的超级离子复合材料是通过对高浓度AGL的AGL-AG_2O-M_XO_Y融化的双旋转式淬火来制备的。 FE-SEM观察结果表明，α-AGL的细颗粒具有直径为几个十纳米的α-AGL均匀分散在玻璃基质中。2）光色素复合材料由SOL-GEL方法制备由杂酸/VIologens和硅胶组成的光致变色复合材料。在溶胶 - 凝胶转化的过程中稳定了杂多酸/VIologens形成的有色物种。3）质子传导性复合材料由Bronsted Acid组成，并通过GOL-GEL方法制备了硅胶和硅胶。此类复合材料的电导率高达10^<-4> -10^<-1> scm^<-1>在室温下。3）auramine 0（au0），其中一种是微度证明的之一，被证明是在掺杂的在湿凝胶的溶胶 - 凝胶转化以及衰老和干燥过程中，监测了硅胶和排放行为。微度周围的Au0在凝胶点没有变化，在干燥过程中急剧增加。
