The observed phosphorescence excitation spectrum of traps in Nh 8 /Nd 8 cannot properly be accounted for by simulations using no more than the Boltzmann populations of the levels in question. We propose an energy transfer model causing broadening of

Direct excitation spectra of the triplet exciton band of deuterated naphthalene are presented. The high resolution spectra (0.1 cm −1 ) of the two Davydov components show a substructure that we attribute to the presence in the crystal of natural tr

We present experimental results on triplet energy transfer from traps to super‐traps and on triplet exciton fusion in substitutionally disordered naphthalene crystals, monitored by the phosphorescence and by the delayed fluorescence of the traps an

A full spectroscopic characterisation of triplet miniclusters of N-h8 in a crystai of N-d8 and their interactions via the lattice states is presented in a two-dimensional lattice. Triplet mini-exciton energy levels, transition moments and polarisatio

Using a model of generating random numbers for 100 × 100 sites of a two-dimensional lattice and the approximation of deep traps, we calculate phosphorescence excitation spectra for N h 8 /N- d 8 mixed crystals. We show that observed spectra are cons

Hopping transport by tunnel effect in a disordered solid often implies a wide spread of the hopping times. This is described here by an ultra-metric space in which the distance between two centres is defined as the longest hopping time on the shortes
