| Abstract: | The electronic fluorescence spectrum of Hg-doped N2/Kr mixed matrices obtained by laser excitation of the Hg3P1 level is composed of the Hg “atomic” (3P1—1S0 and 3P0—1S0) fluorescence and the exciplex fluorescence due to the (Hg—N2)* complex stable in the excited state. The temperature dependence of their intensities and lifetimes was studied in the temperature range 12–24 K. It is argued that the essential part of the 3P0 and exciplex emission is due to two types of Hg sites with one N2 nearest neighbor, differing probably in the orientation of the N2 molecular axis. Strong irreversible effects due to the diffusion of N2 molecules induced by laser irradiation are observed. |
