Determination of Chromaticity Coordinates and Bandgaps of III-V LEDs Using Electroluminescence Spectroscopy
22 August 2018
This article is brought to you by:
In 1907 English engineer Henry Joseph Round was testing the rectifying current behaviour of SiC crystallites and noticed that a faint yellow light was emitted from the SiC; this was simultaneously the first reported observation of the phenomena of electroluminescence spectroscopy and the first successful operation of a light emitting diode (LED). The work of Round was expanded on by a few others in the early 20th century, but it would take many decades for LEDs to become efficient enough for practical use.
LED Professional Symposium and Expo (LpS 2018)
LpS is Europe’s leading international lighting technologies conference and exhibition for design, testing and production of lighting systems, controls and equipment. Now in its 8th year, LpS brings you the greatest minds in lighting together to tackle this year’s key topics of humanising technology, the transformation to the connected world and creative approaches to adapt to the disruption of the lighting industry.
