Applied physics: A light-emitting sandwich filling
Tetsuo Tsutsui
Abstract
Electroluminescence has taken a new turn with the combination of organic light-emitting diodes and inorganic quantum dots. The efficiency of light emission is much higher in the latest easy-to-make device.
On page 800 of this issue, Seth Coe and colleagues1 report the fabrication of high-efficiency organic light-emitting diodes (LEDs) in which the light-emitting centres are cadmium–selenium (CdSe) nanocrystals, or quantum dots. Organic LEDs bring with them the advantages of robust fabrication technique and high performance, which, when coupled with the excellent luminescent properties of nanocrystals, offer exciting prospects for real, workable devices.
