Abstract
The present application discloses a method for preparing an indium phosphide (InP) nanocrystal by using a novel phosphorus precursor as a raw material, and an InP nanocrystal having different wavelengths prepared by the method. The preparation method of the InP nanocrystal includes a step of: using M-(O—C≡P)n as one of reaction precursors, where, M is a metal element, and n is a valence state of the M element. In this present application, M-(O—C≡P)n serves as one of reaction precursors; due to that the metal element M and the element P are from the same reaction precursor, a nanocrystal of a nanocrystal core containing In, P and a metal element M can be prepared.
