Researchers at the University of Chicago revealed groundbreaking developments in the field of infrared technology that could lead to cost-effective sensors soon.

Colloidal quantum dots— semiconductor nanocrystals dispersed in a liquid solution— emit various colors depending on their size and are prevalent in today's gadgets.

Their efficiency, cost-effectiveness, and ease of manufacturing have made them popular in applications such as TVs, where visible light is the outcome.

Philippe Guyot-Sionnest, a professor of physics and chemistry at the University of Chicago, and his team have been looking into the possibilities of leveraging quantum dots to create infrared light.
