The quenching of the characteristic 4f shell emission of Er-doped InP by Auger processes was investigated. For carrier concentrations greater than 3 × 1017 cm-3 the luminescence efficiency weakly depends on free carrier concentration. A theoretical model for quenching of the intra-4f-shell emission was developed in which screening by the outer shell electrons was taken into account. Excellent agreement between theory and experiment for luminescence quenching was noted.
