PROJECT OBJECTIVE

Quantum dots composed of I-III-VI materials such as CuInS2 offer a compelling alternative to typical semiconductor quantum-dot systems, because they have no known toxicity and can be manufactured at a much lower cost. The project proposes to evaluate the commercial viability of CuInS2/ZnS quantum dots for down-conversion in SSL through the development of composites incorporating them. Quantitative evaluation and optimization of the proposed composite materials will include photoluminescence and stability testing. Brightness evaluations and compatibility with commercial silicones will be a priority in Phase I, with spectral tuning and line-width narrowing left to Phase II. Ultimately in subsequent phases, UbiQD will turn its focus from proof-of concept to developing large-scale manufacturing methods for manufacturing the composites in commercial volumes.

PROJECT IMPACT

This project will develop the commercial use of quantum dots composed of I-III-VI materials as an alternative to typical semiconductor quantum-dot systems for SSL down-conversion.
