We present a simple method for the chemical synthesis of InP nanocrystals, which comprises several advantages: (i) the use of simple reagents, namely InCl(3)center dot 4H(2)O and yellow P as the In and P precursors, respectively, and NaBH(4) as the reducing agent in a mixed solvent of ethanol and toluene; (ii) a short reaction time (1-5 h) and low temperature (<75 degrees C); (iii) a high reaction yield approaching 100%. InP NCs in the zinc-blende structure have been obtained as confirmed by powder X-ray diffraction and Raman scattering measurements. Their mean size of 4 rum has been determined by transmission electron microscopy, Raman scattering and absorption spectroscopy.
