Abstract:
The method of plasma-induced thermoluminescence for the first time has been used to investigate the molecular mobility in near-surface nanolayers of molecular crystals (paraffins) with different chain lengths. The investigations have been performed using a NanoLuminograph device (PlasmaChem, GmbH, Germany) under conditions excluding the modifying effect of gas discharge plasma emission on the surface structure under study. The origin of charge stabilization sites on the surface of molecular crystals as well as the influence of the chain length of paraffins and the purity of their chemical composition on the thermoluminescence intensity and the shape of the glow curves have been discussed.
