Excimer Delayed Fluorescence of Compressed Napthalene Crystals.

Abstract:

The compression of naphthalene crystals to 30 kbar at 77K creates, irreversibly, defects in the lattice. These defects capture singlet and triplet excitons, leading exclusively to excimer and delayed excimer fluorescence. Triplet trap depths of about 600cm at 1 atm and about 700cm at 30 kbar are estimated from the temperature dependence of the delayed excimer fluorescence. A wide distribution of singlet trap depths and excimer conformations is indicated by the pressure modifications of the excimer fluorescence band. Author
