Tetrahedral complexes with an excited state consisting of two closely lying triplet states are considered together with the full interaction hamiltonian, including ligand field, Jahn-Teller, pseudo Jahn-Teller, and spin-orbit interactions. The emission band shape is numerically calculated using Monte Carlo integration. The numerical calculations are applied to the PbWO4 system. Previous results using a semiclassical distribution function gave reasonable line shapes, but a mismatch with physical temperature.

Abstract
Tetrahedral complexes with an excited state consisting of two closely lying triplet states are considered together with the full interaction hamiltonian, including ligand field, Jahn-Teller, pseudo Jahn-Teller, and spin-orbit interactions. The emission band shape is numerically calculated using Monte Carlo integration. The numerical calculations are applied to the PbWO4 system. Previous results using a semiclassical distribution function gave reasonable line shapes, but a mismatch with physical temperature. Using the correct quantum distribution function full correspondence with physical temperature is achieved.File in questo prodotto:
