摘要：

Highly luminescent, multiply passivated green- and red-light-emitting quantum dots are used as color converters in InGaN blue LEDs to prepare white LEDs for display backlights. The external efficiencies of green and red QD LEDs reach up to 72% and 34%, respectively. The white LEDs show a luminous efficacy of 41 lm W-1 at 100,000K and color reproducibility of 100% compared to the NTSC standard in CIE 1931. A 46 inch LCD TV panel (see image) using the QD-LED backlight is successfully demonstrated for the first time.
