Synthesis of InP nanocrystals from indium chloride and sodium phosphide by solution route

Indium phosphide nanocrystals have been synthesized by the direct reaction of sodium phosphide and indium trichloride pre-combined with n-trioctylphosphine in 4-ethylpyridine as a suitable solvent for terminating the particles growth. The formation of InP particles with the size of c.a. 3–7 nm was evidenced by the analysis of powder X-ray diffraction, solution UV–vis spectra and transmission electron microscopy.
