Abstract :
The preparation of radiation detectors from semiconducting lead iodide is discussed, and the performance of these devices as X-ray and gamma-ray spectrometers is evaluated. Detectors prepared from melt-grown crystals exhibit good energy resolution for low-energy (<10 keV) X-rays. The energy resolution for higher-energy photons is lower, consistent with the measured values of the electron and hole mobility-lifetime products. Measurements at elevated temperatures show that the detectors continue to operate well over 100 degrees C.<>
