But while this piece is hype, quantum dots have in the past, historically, actually turned out to be the "best" solution in about 50% of the hyped applications. I've used the things in my research, and they do, in some cases, work miracles. One advantage is the they have a sharp red-edge absorption cutoff, so the blue channel would need only a UV removal filter, the green channel only a yellow filter, and the red channel only a red filter. No IR filter needed. Doug McDonald

No IR filter needed. Old news. As I noted before, credentials are quite impressive: Ted Sargent - Chief Technology Officer and Founder Ted holds the rank of professor and Canada research chair in nanotechnology at the University of Toronto. In 2004-6 he was also visiting professor of nanotechnology at the Massachusetts Institute of Technology. In 2003 Mr. Sargent was named "one of the world's top young innovators" by MIT's Technology Review. He was awarded a Canada Research Chair at the University of Toronto in 2000. He received the B.Sc.Eng. (Engineering Physics) from Queen's University in 1995 and the Ph.D. in electrical and computer engineering (Photonics) from the University of Toronto in 1998. -- John "At every crossway on the road that leads to the future, each progressive spirit is opposed by a thousand men appointed to guard the past." -Maeterlinck |
