Transient decay of satellite lines of bound excitons in Si: P

The transient decay of the α and β series of lines in the photoluminescence spectrum of Si: P are reported. The decays of the α lines are compared with the decays of the β lines. The results are consistent with β2 having the same initial state as α3. The results for β1 and β3 are less certain. Their decays are consistent with β1 having the same initial state as either α2 or α3, and with β3 having the same initial states as α4. Overlap between lines, uncertainty in the decay of the boron bound exciton and the presence of unidentified background all make it difficult to make conclusive line assignments.
