<p>A method for preparing metal phosphide nanocrystals is provided to produce nanoparticles having uniform size, to obtain a desired crystal structure selectively, and to produce the metal phosphide nanocrystals having various controlled shapes. A method for preparing metal phosphide nanocrystals by a chemical wet synthesis method includes a step of reacting a metal precursor with a phosphite compound in a solvent to prepare the metal phosphide nanocrystals. A passivation method of a nanocrystal core has a step of adding the metal precursor and phosphite compound to a nanocrystal core-containing solution, and reacting the admixture to grow the metal phosphide layer on the surface of the nanocrystal core. Further, the metal precursor is an organic metal compound or a salts thereof selected from Zn, Cd, Gg, Pb, Sn, Ge, Ga, In, Tl, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Y, Zr, Nb, Mo, Tc, Pd, Ag, Pt and Au.</p> |
