 | Lupton, John Mark | Stimulated emission depletion of triplet excitons in a phosphorescent organic laser | Triplet formation is investigated in an optically pumped polymer laser by detecting the phosphorescence emission after excitation. A clear correlation is observed between the onset of lasing and a saturation of phosphorescence intensity due to stimulated emission depletion of the singlet state and t... | Triplet excitons; Triplet formation; Emission depletion; Phosphorescent organic laser; Optically pumped polymer laser | 2006 |
