(Received February 13, 1976)

An apparatus using a microprocessor is fabricated in order to correct and process the measured photoluminescence data. This is more advantageous for the data correction and processing than those mentioned before; moreover, it can be applied to other spectrophotometries. An application of the apparatus to the photoluminescence spectra measurements of heavily doped n-type GaAs with heat-treatment or ion implantation, is described. It is found that the emission peak at 1.255±0.003 eV (half width: 0.11 eV) is attributed to an excess of arsenic atoms, excess As–Si complex or Ga vacancy-Si complex.
