"Ambient Temperature Isoelectronic Detectors: Status and Prospects

Potential use of high-Z semiconductor detectors operating in the charge collection mode as γ-ray spectrometers at ambient temperatures appears to be limited by charge collection problems. Improvements in present scintillators through improved linearity and higher fluorescent efficiency appear possible. T. C. Madden, et al., 1 suggested the use of isoelectronic scintillators as an improved scintillator material. We have studied the possibility of using one of these, Te doped CdS, as a γ-ray spectrometer.
