| Abstract: | Triplet exciton concentration inferred from delayed fluorescence measurements of pyrene-d10 doped fluorene crystals has been examined as a function of temperature in order to study the correlation between exciton density and electronic triplet spin lattice relaxation (Tie). The results have indicated a poor correlation between the delayed fluorescence intensity and the electronic relaxation rate although a qualitative correlation exists between the growth of trap phosphorescence and relaxation rate. |
