Strem And UbiQD Cadmium-Free QD Deal

Strem will now offer six new CuInS2/ZnS quantum dot products with a range of peak emission wavelengths from 550nm to 950nm and a quantum yield (QY) of over 75 percent

UbiQD, a nanotechnology company, has signed an agreement with Strem Chemicals, to allow distribution of its quantum dot technology.

Strem, a manufacturer and distributor of specialty chemicals for research and development, will now offer six new products in collaboration with UbiQD. These CuInS2/ZnS quantum dots are available with a range of peak emission wavelengths from 550nm to 950nm and a quantum yield (QY) of over 75 percent.

One highlight of these materials is that they are free from the typical quantum dot carcinogens such as cadmium, lead and phosphides. This advantage is based on the greener chemistry used for these products. The CuInS2/ZnS quantum dots also show additional advantages over traditional QDs, such as improved stability, a high quantum yield, and a low self-absorption due to a large Stokes shift (>300 meV).

"Adding our high-performance quantum dots to the Strem catalogue will make these novel nanomaterials available to a significantly broader spectrum of scientists and engineers," said Hunter McDaniel, founder and CEO of UbiQD. "We appreciate when others publishing their research using our dots because it improves our scientific understanding of this complex material system and sometimes helps prove feasibility of new commercial applications."

Strem is looking forward to further collaboration with UbiQD on these pioneering products and applications. "Nanotechnology-based applications continue to grow and Strem is pleased to provide more options for our customers to solve their technical challenges with UbiQD's technology," said Ephraim S. Honig, CEO of Strem Chemicals.
