Abstract

A study was conducted to present a two-step approach to synthesize highly monodisperse indium phosphide (InP) quantum dots (QDs) absorbing from 490 to 650 nm. Initially, InP QDs with an average size of 1.9 nm were synthesized and later used as 'seeds' to grow larger QDs by continuously injecting Zn(In)-P complexes as monomers source. The study used X-ray photoelectron spectroscopy (XPS) to study the oxidation of phosphorus in the synthesized InP 'seeds'. The absence of oxidized phosphorus signal showed the oxide free surface of the 'seed' QDs.
