Polaron Theory Applied to Luminescent Point and Associated Impurities
The effects of interaction of point defects and of donor-acceptor pairs with lattice vibrations in polar solids are reviewed. The Fröhlich polaron formalism is used. The theory is generalized to systems of arbitrarily large associates with arbitrarily large number of bound electronic particles. The case within the adiabatic approximation for which the lattice responds to the stationary distribution of electronic particles is analyzed separately from the polaron case in which the lattice follows the orbital motions of the electronic particles. Some applications to specific materials are considered.
