Jan Buiting @ elektormagazine.com discuss about a new technique used by scientist to build better LEDs.
By manipulating the incident light, researchers of the Complex Photonics Group at University of Twente in Enschede, The Netherlands, have turned light propagating in a layer of scattering nanoparticles into a rising diffusion curve.
By transforming the diffusion curve the result is more light energy being held inside an opaque layer which could lead to better yields for solar cells or LEDs. Even in a medium characterized by randomness, like a collection of non-organized particles that all scatter light, the net spreading of light is uniform. This is typical for diffusion.
