Grad Student Accidently Discovers Ultra-efficient White-Light LED
- jws 18y agoOld article. 2005. Quantum dot LEDs. Original Vanderbilt article is here http://www.vanderbilt.edu/exploration/stories/quantumdotled.html http://www.vanderbilt.edu/exploration/stories/quantumdotled.... (I hope it bypasses their abomination of a web interface, but if not you'll have to learn to navigate to the main part of the article.)
- pmjordan 18y agoIndeed, this is old, I remember reading about it when I was doing research on quantum dots when I was still doing physics at university. I wonder if it's actually been used in practice though, as use of "fake white" LEDs is still abundant. Was it too expensive? Inefficient in power or production? A lot of cool new breakthroughs seem to come out and then nothing is ever heard of them again, and I often find myself wondering "whatever happened to that?"
- nazgulnarsil 18y agoI think this happens to everyone. How about a website that tracks down old (2 years or more) "Breakthrough technology" articles and gives updates on what's going on? I know I'd browse such a site. actually isn't this what worldchanging.com should be doing?
