Scientists uncover a process that stands in the way of making quantum dots brighter
Scientists uncover a process that stands in the way of making quantum dots brighter Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots’ light-producing efficiency. A new study explains why, and the results have broad implications for developing future quantum and photonics technologies where light replaces electrons in computers and fluids in refrigerators, for example. In a QLED TV screen, dots absorb blue light and turn it into green or red. At the ...
