Quantum Materials Corp. (San Marcos, Texas) is one

Quantum Materials Corp. (San Marcos, Texas) is one of the hopefuls. Although not exhibiting at Display Week, QMC announced in a June 1 press release that it had “launched their new QDX class of high-stability cadmium-free quantum dots….” The release continued, “QDX quantum dots have been tested to withstand heat resistance to 150°C for 4 hours with no oxidation performance degradation in an open-air environment.” When I asked him, QMC PR person Art Lamstein told me the company is in a “pre-revenue” stage. In addition to the company’s original cadmium-based quantum tetrapods based on a Rice University patent, QMC is now also making indium-phosphide dots based on a Bayer patent the company purchased in 2014.
