Light Extraction by Changing Composition of Material

Education Level
High School

This activity has been designed to have students explore light emitting diodes (LED) and the importance of index of refraction in improving LED efficiency. This activity investigates the tune-ability of a polymer’s index of refraction by using a macromodel LED. This activity will be a macromodel because the size of nanoparticles is smaller than the smallest wavelength of visible light.
