Radioluminescence mechanism and charge transport phenomena in organic solids

The overview of our previous works devoted to development of the modern the ory of tile radioluminescence of organic condensed media is given in this p aper to show that Prof. E.A. Silinsh ideas have been conformed by this theo ry as well as by well-known experimental facts of scintillation technique. Only some of his ideas are discussed namely, the Gaussian distribution mode l for local energetic states of a polarization origin in an organic crystal energy diagram, and the molecular - lattice polaron model. It is shown tha t the appearance of very shallow trapping centres of polarization origin ca use the additional delay of a moment of a radioluminescence photon emission in organic solid scintillators.
