✦ Synopsis

We present a combined fluorescence and hole-burning study of the biliprotein C-phycocyanin. Sharp zero-phonon holes compare with a broad structureless fluorescence. This finding is rationalized in terms of the special level structure in this pigment, the fast energy-transfer processes and a lack of correlation of the energies of the emissive states.

A theoretical model is presented which describes quantitative!y the elimination of the inhomogeneous broadening in luminescence spectra of impurity centres on site-selective laser escitation. The model esplains our expcrimenial data showing a remarkable dependence of the cxitation selectivity on the
