The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...

Scientists with the University of Chicago have demonstrated a way to create infrared light using colloidal quantum dots. The researchers said the method demonstrates great promise; the dots are ...

Getting a molecule to do what you want it to do is not always easy. An organic molecule will absorb only certain wavelengths of light based on its arrangement of electrons, which can be difficult to ...
