| Abstract: | Radiative recombination in amorphous phosphorus is studied by the technique of time-resolved photoluminescence. In the first 200 ns following excitation the luminescence band moves from 1.36 to 1.18 eV. The position of the band is also shown to depend on the energy of exciting photons. These observations are discussed in terms of Coulomb interaction and thermalisation, and their implication for a detailed modelling of excitation and radiation assessed. |
