Nanosys scientific co-founder and Director of the Lawerence Berkeley National Lab, Dr. Paul Alivisatos, takes NBC Learn on a tour of Nanosys' Silicon Valley Quantum Dot manufacturing facility.
Dr Alivisatos, who recently received the 2016 National Medal of Science, talks with NBC reporter Kate Snow about how this amazing nanotechnology that he helped pioneer is changing the way our TVs work today:
SNOW: When quantum dots of different sizes are grouped together by the billions, they produce vivid colors that have changed the way we look at display screens. The initial research, funded by the NSF, has found its way into many applications, including a nanotechnology company called Nanosys, which produces 25 tons of quantum dot materials every year, enough for approximately 6 million 60 inch TVs.
ALIVISATOS: What we have here is a plastic film that contains inside of it quantum dots, very tiny, tiny crystals made out of semiconductors. It actually contains two sizes of nanoparticle - a very small size that emits a green color and a slightly larger size that emits a red color of light.
SNOW: This film is embedded into tablets, televisions, and laptops to enhance their displays with brilliant color.
ALIVISATOS: One of the things that we've learned about vision is that we have receptors in our eyes for green, red and blue colors. And if we want a really high quality display, we need to match the light emission from our display to the receptors in our eyes.
