Cadmium-Free Quantum Dot Technology in LED Lighting
Nanoco’s joint agreement with Osram has been in place since 2011 with the objective of delivering LED lighting with superior performance characteristics. Much of the technical work to date has focused on encapsulating Nanoco’s cadmium-free quantum dots so they can withstand the operating conditions associated with LEDs. This latest, 12-month agreement with Osram will further that product development.

Researchers from Oregon State University Develop Quantum Dot Technology that may Help Light the Future
Advances at Oregon State University in manufacturing technology for quantum dots may soon lead to a new generation of LED lighting that produces a more user-friendly white light, while using less toxic materials and low-cost manufacturing processes that take advantage of simple microwave heating.
A key to the advances, which have been published in the Journal of Nanoparticle Research, is use of both a “continuous flow” chemical reactor, and microwave heating technology that’s conceptually similar to the ovens that are part of almost every modern kitchen.
The continuous flow system is fast, cheap, energy efficient and will cut manufacturing costs. And the microwave heating technology will address a problem that so far has held back wider use of these systems, which is precise control of heat needed during the process. The microwave approach will translate into development of nanoparticles that are exactly the right size, shape and composition.
“There are a variety of products and technologies that quantum dots can be applied to, but for mass consumer use, possibly the most important is improved LED lighting,” said Greg Herman, an associate professor and chemical engineer in the OSU College of Engineering.
