A strong visible ã3u+X̃1g+ luminescence was observed upon the UV excitation of cryogenic rare gas (argon, krypton, and xenon) matrices doped with dicyanoacetylene (NC4N). Spectra and lifetimes of this phosphorescence have been measured. A detailed analysis of resolved vibronic bands is presented.

PACS: 33.50.Dq Fluorescence and phosphorescence spectra.

Key words: matrix isolation, phosphorescence, dicyanoacetylene, cyanopolyynes.
