Badania warstw związków organicznych o właściwościach paramagnetycznych z uwzględnieniem procesu samoorganizacji i badań materiałów biologicznych

W pracy przedstawiono badania paramagnetycznych rodników nitroksylowych oraz znakowanych spinowo polipeptydów zaadsorbowanych na dobrze zdefiniowanych powierzchniach. Wyniki eksperymentalne zostały uzyskane przy pomocy technik mikroskopowych (STM, AFM, mikroskopia optyczna), spektroskopowych (EPR, XPS) oraz rozwijanej w ostatnich dekadach techniki ESN-STM.Zintegrowany Program Operacyjny Rozwoju Regionalnego i Programu Operacyjnego Kapitał Ludzki (Doktoranci - Regionalna Inwestycja w Młodych Naukowców

Fluorescent imaging of heavy charged particle tracks with LiF single crystals

Radiophotoluminescence of F2 and F3 + color centers in LiF was exploited for imaging tracks of energetic heavy charged particles. LiF crystals were irradiated with helium, carbon, neon, silicon and iron ions at the HIMAC accelerator in Chiba, Japan. The patterns created by radiation were visualized with a wide-field fluorescent microscope under blue-light excitation. The shape of the visible tracks was found not to depend on ion type and energy. The full width at half maximum of track profiles was in all cases around 500 nm, what corresponds with the resolution limit of the microscope, which was estimated to be 420 nm. On the other hand the fluorescent intensity of tracks was found to increase in a linear manner with the increasing LET. This indicates possibility of obtaining some spectrometric information on the radiation field
