Researchers of the Optoelectronics and Measurement
Techniques Unit (OPEM) at the University of Oulu have invented a
new method of producing ultra-sensitive hyper-spectral
photodetectors. At the heart of the discovery are colloidal quantum
dots, developed together with the researchers at the University of
Toronto, Canada. Quantum dots are tiny particles of 15-150 atoms of
semiconducting material that have extraordinary optical and
electrical properties due to quantum mechanics phenomena. By
controlling the size of the dots, the researchers are able to
finetune how they react to different light colors (light
wavelengths), especially those invisible for the human eye, namely
the infrared spectrum.
