A time-resolved luminescence spectroscopy system equipped with one GaAs PMT, one InGaAs PMT, and three MCT detectors allows measurements in the wavelength range of 0.3 microns to 12 microns. The system is capable of measuring time-resolved photoluminescence and electroluminescence from 10 K to 400 K with nano second resolution. This system is designed to be integrated with our low-temperature probe station.
