摘要：
Prolonged luminescence of tryptophan and indole in liquid solutions of different polarity has been registered in a microsecond time-scale at room temperature; by nature it differs from phosphorescence or delayed fluorescence of P and E types. The data presented suggest that the observed prolonged luminescence is caused by recombination of the radicals formed upon UV irradiation of indole chromophores by laser pulses.
