Synthesis and electrochemical properties of InP nanocrystals

In this report, we present a new organometallic synthetic method to prepare nearly monodisperse InP nanoparticles using indium trifluoroacetate as the In precursor. Spherical particles of various sizes were prepared by modulating the growth duration. The optical and electrochemical properties were investigated and discussed with reference to band edge positions. This is the first report on the band edge position of quantum confined InP nanoparticles, which is a key parameter for development of electro-optic devices like solar cells and light-emitting diodes based on it.
