We investigate the parameters in the band-anticrossing (BAC) model for GaNP and InGaPN in this work. The parameters in the BAC model for GaNP and InGaNP are obtained by fitting experimental data. It is found that the band gap bowing of InGaNP is stronger than that of InGaNAs. The effects of annealing on the parameters in the BAC model for InGaNP are also discussed in this work. In addition, the origins for improving luminescence efficiency by annealing are explained. It is relative to the forming of more In-N clusters.
