Phosphorescence spectra recorded with vapor-deposited glassy phenanthrene layers reveal the existence of several inhomogeneously broadened monomeric triplet traps of structural origin and two excimeric triplet traps. Temperature-dependent studies yield estimates for both the triplet excimer binding energies and the parameters governing triplet trapping kinetics.
