Abstract

The measurement of photoluminescence or electroluminescence on solid samples can provide details on the electronic nature of the material in question. The majority of these measurements involve the examination of the electronic structure of semiconductors, especially those under consideration for use as light-emitting diodes or photoelectric cells. The presence of defects in these materials (in the form of excitons and acceptor/donor centers) can dramatically alter the observed spectral properties. However, the technique is largely limited to electronic profiling, so significant structural information and sample morphology must be probed with complementary techniques. Basic instrumentation and techniques for recording these spectra are presented, along with special considerations for solid-state samples. Numerous examples of recent literature reports utilizing this technique are also presented.
