Katodoluminiscence polysilanů
Horák, Petr ; Schauer, Petr
Polysilanes - a broad class of organic materials whose basic building block is built up of silicon substituted by alkyl or aryl groups. Properties of these substituents significantly affect properties of polysilanes. This material is very interesting because of its chemical, electrical and optical properties. In spite of great research interest in recent years cathodoluminescent (CL) properties of polysilanes were not yet studied. Poly[methyl(phenyl)silane] (PMPhSi) is a typical representative of polysilanes which was prepared by the Wurtz coupling polymerization. Thin layers of PMPhSi were prepared from toluene solution by a spin coating technique. The material was applied on the quartz glass substrate and covered with the aluminium (Al) film. The Al film protected the specimen from charging and reflected photons emitted under the specimen surface towards the quartz glass substrate
