Abstract

This paper reports on the evaluation of photodetectors fabricated from a ternary semiconductor, TlBr/sub x/I/sub 1-x/ for application in scintillation spectroscopy. These photodetectors are characterized in terms of their resistivity, charge transport parameters, quantum efficiency as a function of wavelength, and finally their performance as scintillation spectrometers. The details about TlBr/sub x/I/sub 1-x/ purification, crystal growth and device fabrication are also addressed.<>
