Abstract:

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.
