Expected educational outcomes Students will gain an introduction to the concepts of electroluminescence, spectroscopy, and semiconducting polymers. Students will learn how to use a spectrometer to make an electroluminescence measurement. Students will learn how to measure the electroluminescence spectra of LEDs made from inorganic materials or semiconducting polymers. Students will learn how electroluminescence spectra depend on chemical structure and material morphology. The procedure consists of recording the electroluminescence spectrum of each LED using the Ocean Optics spectrometer.
Students then plot their results and compare the spectra.
