Ternary synthesis of colloidal Zn3P2 quantum dots†
Abstract
The synthesis and characterization of crystalline colloidal zinc phosphide quantum dots with observable excitonic transitions ranging between 424–535 nm (2.3–2.9 eV) are reported. A ternary combination of ZnEt2, Zn(O2CR)2, and P(SiMe3)3, forms a pentanuclear zinc cluster on mixing followed by conversion to (Et2Zn)P(ZnO2CR)2(SiMe3) in a rate-determining step prior to quantum dot formation.
