QD Vision Wins EPS's Green Chemistry Award

Facebook X LinkedIn Email
QD Vision Inc. has received the 2014 Presidential Green Chemistry Challenge Award for its approach to quantum dot technology for energy-efficient commercial display and lighting products.

The designation, awarded by the U.S. Environmental Protection Agency, recognizes chemical technologies that incorporate the principles of green chemistry in chemical design, manufacturing and use. Such technologies can reduce or eliminate the generation and use of hazardous substances.

In developing their quantum dot technology, QD Vision employs processes that use fewer hazardous building blocks and solvents, reduce solvent waste, increase yields and ensure a net positive environmental benefit. The production of semiconductor quantum dot technology typically involves hazardous chemicals and low yields.

This award is sponsored annually by the EPA’s Office of Chemical Safety and Pollution Prevention, alongside the American Chemical Society Green Chemistry Institute.

Glossary
quantum dots
A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
