Two possibilities of photon collection from the luminescence centra can be applied at cathodoluminescence (CL) measurement of transparent specimens. The CL emission can be collected both from the side of excitation and substrate using a lens and a light guide, respectively. To choose the better alternative, one has to study optical properties and electron-interactive volumes of specimen materials. Based on this knowledge, optimized geometry, dimension and arrangement of the specimen can be designed. The object of our interest was the CL study of Poly-(Methylphenylsilylene), i.e. PMPhSi, which is an interesting material both from the application and the basic research point of view. The PMPhSi was prepared by the Wurtz coupling polymerization [1]. The low-molecular weight fractions were extracted with boiling diethyl ether. The layers for the CL measurements were prepared from a toluene solution by casting on quartz disk substrates.
