A BRIGHT FUTURE FOR QUANTUM DOTS

FIRST CONTINUOUS PROCESSING METHOD

Quantum Materials Corp. LLC (QMC; San Marcos, Tex.; www.qmcdots.com) has developed what is said to be the world’s first continuous production process for QD manufacturing. QMC’s technology uses all fluidized materials and continuous-flow reactors, whereas the vast majority of QD production depends on batch production. “We use microflow reactors, which can achieve high rates of heat and mass transfer, resulting in a very uniform product. Therefore, very little post-processing is required,” explains Krishna Kowlgi, senior research engineer at QMC. In addition to product homogeneity, another benefit of continuous QD processing over batch is time — the entire continuous-flow process can be automated and requires much less manual intervention. “From start to finish, it takes a minimum of 5 s to a maximum of 19 min, based on the QD material type, to convert raw materials to functional QDs. We think this is the fastest QD production currently on the market. The numbers in literature for batch QD processes range from multiple hours to days or even weeks,” adds Kowlgi. He emphasizes that QMC’s reactors are flexible enough to produce different QDs for different end uses. “The light-emission capabilities of the QD depends on its geometry and chemical composition. A 4-nm spherical QD would produce different emissions than one with a 3-nm diameter,” he adds. Due to the fluidized flow chemistry of QMC’s process, QDs are produced in solution, so they are either filtered or undergo some other type of post-processing separation step.
