Application Note: Determination of Chromaticity Coordinates and Bandgaps of III-V LEDs Using Electroluminescence Spectroscopy

Modern LEDs are efficient, bright and reliable and are one of the most versatile and widely used light sources with an ever increasing number of applications. In this application note the FS5 Spectrofluorometer, equipped with the electroluminescence accessory, is used to investigate the emission properties of four type III-V LEDs and determine their bandgaps and chromaticity coordinates.
