Fabrication of Cd0.5Zn0.5S:Cu QDs incorporated organically modified SiO2 films showing entire visible colour emission with high quantum yield

Abstract

Multicoloured fluorescent nanocomposite films containing homogeneously dispersed Cu ion-doped Cd_0.5Zn_0.5S alloy QDs capped by P123 and organically modified SiO₂ have been fabricated. The concentration of QDs in the film is as high as 40 mol% with respect to the equivalent SiO₂. The cured transparent films showed strong photoluminescence covering the entire visible window with very high quantum yield ensuring applications.
