Recombination radiation in GaAs diodes has been found proportional to the forward diode current at current levels where the recombination radiation is dominant, implying an efficient conversion from injected electrons to band-edge photons. A visible red radiation has been observed from these diodes at high forward diode currents.
Black et al. (1963) studied this question.
