What’s in a screen? It might be tiny particles called quantum dots – a novel material for everything from screens to solar cells. But how do researchers optimize new materials like quantum dot films? One type of spectroscopy – called transient absorption – could help.
Lasers are cool – everyone who’s seen a sci-fi movie knows that. But we still haven’t figured out how to use them to their full potential in real life. This paper explores some ways to improve the efficiency of quantum dot lasers, which have a myriad of applications in computers to cell imaging.
