Název v původním jazyce

Cathodoluminescence as a method for the study of degradation of polysilanes

Popis výsledku v původním jazyce

The paper presents a unique cathodoluminescent (CL) method suitable for studying polysilane properties and the first CL characteristics of the material being investigated. Poly[methyl(phenyl)silylene] (PMPSi) was selected as a typical representative of polysilanes. The PMPSi study was based on the measurement of the intensity of CL emission after passing through the specimen. The major problem of this study is the susceptibility of the material being investigated to the degradation by electron beam. PMPSi degradation strongly decreases the CL intensity. Therefore, detection in the synchronous mode was used to eliminate the influence of the background and of the noise. It was found that the degradation process is partly reversible. A partial recovery ofintensity was attributed to reverse recombination reactions of silyl radicals in a vacuum after 20 h of annealing at room temperature.
