Irradiation test of GaAlAs heterojunction infrared emitting diode OP224 and NPN-silicon phototransistor OP604 were performed by using 60Co γ-rays.The cumulative effect of oxide-trap charge and interface-trap charge under 60Co γ-rays irradiation were analyzed.The results showed that as the irradiation dose increased
the maximum forward current and the infrared light intensity of GaAlAs heterojunction infrared emitting diode OP224 gradually decreased;the dark current of NPN-silicon phototransistor OP604 gradually increased
