Economic Synthesis of High Quality InP Nanocrystals Using Calcium Phosphide as the Phosphorus Precursor

InP nanocrystals of low size dispersion are synthesized in 1-octadecene using indium myristate and PH3, in situ generated from the air-stable and low-cost precursor calcium phosphide. The obtained nanocrystals exhibit size-dependent emission (570–720 nm), and their fluorescence quantum yield reaches 22% after overcoating with a ZnS shell.
