以空气稳定、低成本的磷化钙为前驱体，采用十四烷酸铟和PH_3在1-十八烯中原位合成了低尺寸分散的InP纳米晶。所得纳米晶体具有尺寸依赖性的发射（570-720 nm），并且其荧光量子产率在用ZnS壳包覆后达到22%。
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.
