Getting the green light: ZnS-coated Cd1−xZnxSe alloy nanocrystals are stable and efficient emitters, whose color can easily be tuned in the blue–green spectral range by changing the ratio of the metal precursors applied during synthesis. Incorporated into a polymer matrix, they can be used for the conversion of blue (see image, top) or UV (bottom) light to green light at 530 nm.
