A Japanese research group successfully controlled the diameter of a semiconductor nanoparticle having a novel composition of (AgIn)xZn(1-2x)S (silver, indium, zinc, sulfur) by photoetching so it would emit fluorescent light in various colors.
The group is led by Susumu Kuwabata, a professor at the Graduate School of Engineering of the Osaka University, Tsukasa Torimoto, a professor at the Graduate School of Engineering of the Nagoya University, and IDEC Corp.
Potentially, research into semiconductor particles like this could boost energy efficiency in light sources.
