A facile approach to synthesize high-quality ZnxCuyInS1.5+x+0.5y nanocrystal emitters

A facile approach to synthesize ZnxCuyInS1.5+x+0.5y nanocrystal emitters was presented. The compositions of these nanocrystals were precisely controlled, and the relative PL quantum yields were up to 40%, with tunable emissions in 450–640 nm.
