Abstract
The invention provides a method for repairing the performance of a cadmium zinc telluride radiation detector based on sub-forbidden band illumination. The method solves the technical problem that the performance of an existing cadmium zinc telluride radiation detector is degraded or fails due to environmental factor damage in the service period. The method comprises the steps of preprocessing tellurium-zinc-cadmium crystals, preparing a detector and preparing a sub-forbidden band illumination detector. The method is low in cost, simple to operate, safe, reliable, environment-friendly and energy-saving.
