Surface relaxations of selectively excited rare-gas doped rare-gas solids

Surface relaxations of selectively excited rare-gas doped rare-gas solids include desorption of excited atoms and the formation of atomic P-3(1) and P-3(2)-type surface centers as well as of homonuclear and heteronuclear molecular centers. Time-resolved luminescence spectra originating from these centers indicate that the long-living P-3(2)-type centers act as reservoirs for the formation of the molecular type centers.
