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 low energies where TV screens operate, this conversion of light from one color to another is virtually 100% efficient. But at the higher excitation energies required for brighter screens and other technologies, the efficiency drops off sharply. Researchers had theories about why this happens, but no one had ever observed it at the atomic scale until now.

Feature open Meredith Smith, Kari Apter and Samantha Hornback Congratulations to the 118 members of the 2021 class of OSA Fellow Members, who will be recognized at OSA conferences throughout the year for scientific, engineering and technological contributions, as well as industry leadership and service to OSA and the global optics community. The 2021 class of Fellows reflects the diverse and inclusive community that OSA serves. A record 261 nominations were received, making this program very competitive as no more than 10% of OSA’s total membership may be elected as Fellows. For more information, contact the OSA Awards Office (awards@osa.org; +1 202.416.1960) or go to www.osa.org/fellows.. Nominations for 2022 Fellows are due by 15 June 2022.

Nanotechnology Now Home > Press > Controlling chemical catalysts with sculpted light Depiction of the experimental setup where palladium nanorods lie atop gold nanobars. In this image, an electron beam is directed at the sample to watch the catalytic interactions between the hydrogen molecules (in green) and the palladium catalyst. The light driving the illumination is shown in red. CREDIT Katherine Sytwu Abstract: Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process - and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction. But what if one could convince the unengaged parts of a catalyst to get involved? Chemical reactions could occur faster or more efficiently.
Date Time Stanford engineers find a way to control chemical catalysts with sculpted light Using state-of-the-art fabrication and imaging, researchers watched the consequences of adding sculpted light to a catalyst during a chemical transformation. This work could inform more efficient – and potentially new – forms of catalysis.
