A Bright Future: Quantum Dots and the Quest for Energy Efficient White Lights

From stadium lights to night lights, the modern way of life runs on artificial illumination. This lighting is costly--in both environmental and economic terms--but last week in the journal Optica, a team of researchers from Koç University in Turkey introduced a new kind of white light source, based on blue LEDs and quantum dots, that could lower the costs of lighting up our world. Containers of red and green quantum dots illuminated under ultraviolet light. Image Credit: Sedat Nizamoglu, Koç U...
