采用静电自组装技术在石英玻璃光纤和显微镜载玻片上制备了二氧化钛胶体与阴离子聚电解质 PSS、二氧化硅胶体与阳离子聚电解质 PDDA的复合薄膜 ,研究了薄膜的光反射性能 .在光纤端面上交替沉积光学厚度为λ/4的 PSS/Ti O2 高折射率薄膜和光学厚度为λ/4的 PDDA/Si O2 低折射率薄膜 ,可以获得λ/4多层高反射膜 ,使样品表面的反射性能大大提高 .
Electrostatic self-assembly technique was used to fabricate composite thin films of titanium dioxide colloid, anionic polyelectrolyte PSS, colloidal silica and cationic polyelectrolyte PDDA on quartz glass optical fiber and microscope glass slides. The optical reflectivity of the films was investigated. By depositing PSS / Ti O2 high refractive index film with λ / 4 optical thickness and PDDA / Si O2 low refractive index film with λ / 4 optical thickness, λ / 4 multilayer high reflection film can be obtained to make the reflection performance Greatly improve .
