Abstract
A detection system comprises a semiconductor layer for converting x-ray photons or particles into charge carriers and a light emitting layer for generating light from the charge carriers. A computer system obtains images generated by the camera and tracks the response of the detector to x-ray photons and/or charged particles over time in order to spectrally resolve the energy of the x-ray photons or particles.
