86% Informative

Empa researchers are working on miniaturized IR detectors made of quantum dots.

Colloidal quantum dots can be applied to different materials by means of spin coating or printing.

They are cheaper, more energy-efficient and more flexible than conventional semiconductors.

One possible application of this technology would be smart textiles.

Their task now is to make this promising technology even faster, cost-effective, more flexible and more sustainable.
