    Temperature dependence of the intensity of fluorescence of poly(n-vinylcarbazole) films

    The fluorescence spectra of thin films of poly(N-vinylcarbazole), PVCA, were measured at temperatures between 103 K and 535 K by constant excitation light intensity. Below 300 K, the corrected spectra were div...

    Drift mobility of holes in some photoconductive polymeric structures in the glass transition region

    Drift mobility of holes in poly(N-vinylcarbazole) PVCA and its mixtures with poly(N-epoxypropylcarbazole) PEPCA was measured in a broad temperature range. Sensitivity of charge transport to the dynamic phenome...

    Energy spectrum of α particles emitted from sources of different thicknesses

    The shape of the energy distribution of all α particles emitted by sources of different thicknesses was investigated. The energy distribution N(E) dE found can be expressed by a semi-empirical formula, which on ...
