Abstract :
The intrinsic resolution of low energy photopeaks with CdTe detectors is shown to be improved if the detectors are illuminated with a GaAs electroluminescent diode. Time of flight measurements on this CdTe material exhibit a strong modification of the current response under a given monochromatic infra-red illumination. The interpretation involves trapping effect and its optical quenching.
