| Description
| - Práce předsatvuje unikátní katodoluminiscenční (CL) metodu, vhodnou pro studium vlastností polysilanů a rovněž první CL charakteristiky zkoumaného materiálu. Jako typický zástupce polysilanů byl vybrán Poly[methyl(phenyl)silylene] (PMPSi). Studium PMPSi bylo založeno na měření intensity CL emise po průchodu vzorkem. Hlavní problém tohoto studia je náchylnost vyšetřovaného materiálu k degradaci elektronovým svazkem. Degradace PMPSi silně snižuje Cl intensitu. Z tohoto důvodu byla použita detekce v synchronním módu, která omezila vliv pozadí a šumu. Bylo zjištěno, že degradační proces je částečně vratný. Částečné obnovení intensity, po 20 hodinách temperování ve vakuu při pokojové teplotě, bylo přisouzeno reakcím zpětné rekombinace silyl radikálů. (cs)
- 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 of intensity was attributed to reverse recombination reactions of silyl radicals in a vacuum after 20 h of annealing at room temperature.
