Triplet population and depopulation rates of single TERRYLENE (cas 188-72-7) molecules in p-terphenyl crystal

Add time:09/30/2019    Source:infona.pl

Fluorescence intensity correlation functions of single TERRYLENE (cas 188-72-7) molecules in p-terphenyl crystals were measured within the temperature range 5–300K. The analysis provided the population (k 23 ) and depopulation (k 31 ) intersystem crossing (ISC) rate constants of the lowest excited triplet state T 1 . These rates increase continuously with temperature, without any noticeable change at the 193K, temperature of the order–disorder phase transition in p-terphenyl crystal. The depopulation channel composed of the exciting light intensity dependent T 1 →T n absorption followed by the T n →S 1 ISC is important at higher temperatures.
