摘要：

Out of the blue: (CdS)ZnS nanocrystals suitable for display applications have been prepared and exhibit a narrow, blue luminescence from 460 to 480 nm (FWHM ≤28 nm; see picture), with quantum efficiencies of 20-30%. It is possible to demonstrate blue electroluminescence from these core-shell nanocrystals by embedding them in an organic thin-film device.
