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

Abstract

A facile approach to synthesize Zn(x)Cu(y)InS(1.5+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.
