Quantum Materials Begins Shipping of Cadmium-Free QDs

Photonics Spectra
Apr 2015
Quantum Materials Corp. has begun shipping cadmium-free red and green quantum dots in evaluation and production quantities to consumer electronics manufacturers.

The company said a new facility, equipment and personnel have allowed it to increase the uniformity and enhanced the stability of its QDs. It plans to increase production to 2000 kg per year starting in the second quarter.

Electronics manufacturers seeking to stay ahead of environmental regulations are seeking out cadmium-free QDs, the company said. The nanoparticles can be integrated into standard thin-film roll-to-roll inkjet and surface deposition technologies used on LCD production lines.

Quantum Materials said its products make energy efficient and environmentally friendly components for displays, solid-state lighting, solar photovoltaic power applications, advanced battery and energy storage solutions, biotech imaging and biomedical theranostics.
