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.
