Abstract
In this report the dual amplified spontaneous emission (ASE) characteristics of coumarin 138 (C138) had been studied, under different solvent environments. The results obtained were compared with coumarin 461 (C461) and coumarin 450 (C450), which have closely related structure. The results showed that all these dyes could produce ASE from superexciplex – a new molecular species – formed only under high inversion densities, obtainable by pulsed laser excitation. We have strong indication that a superexciplex with TICT conformation is capable of producing strong ASE.
