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.

One of the most powerful techniques to understand the behaviour and performance of electrical devices is electroluminescence spectroscopy. In this application note the FLS1000 Photoluminescence Spectrometer is used to investigate the emission properties of a phosphor coated indium gallium nitride white light LED using both steady state and time-resolved electroluminescence spectroscopy.

Hybrid halide perovskite semiconductors show excellent promise as a new generation of solid state light emitters. In this application note the CIE colour coordinates and the excited state lifetimes of a promising white light emitting perovskite are measured using the FLS1000 Photoluminescence Spectrometer.
