摘要：

Green to the core: CdxZn1-xSe alloy core nanocrystals are synthesized and overcoated with CdyZn1-yS to create core-shell nanocrystals with the ideal wavelength of emission for quantum dot light-emitting device (QD-LED) displays. These (CdxZn 1-xSe)CdyZn1-yS core-shell nanocrystals are used to fabricate color-saturated green-emitting QD-LEDs (see picture), which are suitable for display applications.
