Abstract

LiZn and LiCd vapour mixtures prepared in the heat-pipe oven are irradiated with pulsed excimer laser emission at 308 nm. Temporal evolution of the fluorescence spectra is observed showing that different processes occur such as multiphoton excitation, collisional energy transfer, photochemical reaction, relaxation etc. Temporal change of the LiZn and LiCd blue-green diffuse bands spectral shape is observed and interpreted in terms of previous spectral simulations. The effective lifetimes of different spectral features are determined.
