Light emitting diodes belong to a class of lighting technology called solid state lighting that use semiconductor diodes instead of filaments, plasma or gas for illumination. We have entered an era of advanced LED technology, and consequently, an enormous global market has developed for LED lights. The following blog, an excerpt from the BCC Research report “Solid-state Lighting: Technologies and Global Markets” provides a short introduction to LED technology.

The principles of Raman spectroscopy have been understood for the past 80 years and are based on the Raman effect, the phenomenon of inelastic scattering of light (Raman scattering), which was discovered by Dr. C.V. Raman in 1928. In the years following its discovery, Raman spectroscopy was used to provide the first catalog of molecular vibrational frequencies.
