The development of the light emitting diode (LED) has revolutionised the lighting and display industries. The immense impact of the LED was recognised by the award of the 2014 Nobel Prize in Physics to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for the “invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources". 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 steady state and time-resolved electroluminescence spectroscopy.
