Abstract
The subject of the invention is a method of synthesizing a compound MxPy where M is an element belonging to one of columns II to XV of the Periodic Table of the Elements or to the family of lanthanides or to the family of actinides, characterized in that it includes the reaction of x moles of compound comprising the element M in its oxidation state 0 with y/4n moles of compound (P4)n.The method of the invention may be carried out at a temperature much lower than those necessary in the methods of the prior art. It also allows low-temperature formation of nanoparticles and stoichiometric reaction control.The applications of this method are numerous: magnetic ferro-magnets for MnP and FeP; hydrodesulfurization catalysts for Ni2P; luminescent nanoparticles for biological applications; microelectronics and optoelectronics for InP; and electronics for GaP. The latter two phosphides are also used in the photovoltaic energy field.
