The integrating sphere collects external radiation from an optical source or device (such as a laser or a light emitting diode) usually for the purpose of flux measurement. Radiation introduced into an integrating sphere is dispersed very uniformly at the sphere walls. The resulting integrated radiation level is directly proportional to the initial radiation level and can be directly measured by a detector.

The LeRoy Eyring Center For Solid State Science here at ASU allows materials characterization, including transmission electron microscopy (TEM), scanning electron microscopy (SEM) Secondary Ion Mass Spectrometry (SIMS), Atomic Force Microscopy (AFM), and X-ray measurements.

The Oriel QE/ICPE Kit is a turn key system from Newport for spectral quantum efficiency measurements of solar cells. It includes a 150W xenon arc lamp, Cornerstone 260 1/4m monochromator complete with chopper and filter wheel attached, current preamplifier, Merlin digital lock-in amplifier, calibrated silicon detector head and TracQ Basic software interface for automated spectral QE measurements.

In addition, two 300W xenon arc lamps supplied by Newport provide additional light…

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.
