Electronic excitation of the surface of UV-irradiated solids in heterogeneous recombination of hydrogen atoms

详细

The reaction energy transfer to electrons and release of electrons from traps under the action of the recombination of H atoms on the surface of light-sum-storing crystals (Zn₂SiO₄–Mn, ZnS, ZnS,CdS–Ag) was studied. This effect is associated with the reaction energy accommodation via the electronic channel. The transfer of electronic excitations to the atomic recombination event is independent of the reaction rate, but depends on the electron transition energy in a solid. The possibility of electronic excitation per heterogeneous recombination event of H atoms increased exponentially as the electron transition energy decreased.
