Definitions

  • the present invention provides a method of preparing nanoparticles of one or more group IV metals or alloys thereof comprising the steps of: reacting, under an inert atmosphere, at atmospheric pressure and with heating, one or more group IV metal precursors with a decomposition-promoting reagent in a liquid reaction medium comprising a high temperature surfactant; adding a surface-bonding agent; and recovering the nanoparticles.
  • the method of the invention includes a further step of adding a quenching agent prior to adding the surface-bonding agent.
  • the step of adding a quenching agent is prior to adding the surface-bonding agent but after adding the decomposition-promoting reagent.
  • the surface-bonding agent may also act as the quenching agent.
  • the surface-bonding agent comprises an alkenyl or alkynyl moiety.
  • the method includes a further step of purifying the nanoparticles.
  • the method produces nanoparticles with a chemical reaction yield >50%; more preferably >60%.
  • Suitable L groups include, but are not limited to: —NH 2 ; —COOH; —CONH 2 ; —OH; —CHO; —SO 3 H; —PO 3 H 2 ; —PH 2 ; —SH; —CH ⁇ CH 2 ; —C ⁇ CH; —Cl; —F; —Br; and —I.
  • alkenyl is intended to include optionally substituted straight chain, branched chain and cyclic mono-unsaturated hydrocarbon groups.
  • nanoparticle As used herein, the terms “nanoparticle”, “nanocrystal” and “quantum dot” refer to any particle less than 100 nanometers in size.
  • This reaction mixture is usually heated to the reaction temperature during step a), although it is possible to heat the mixture to the reaction temperature during step b).
  • np indicates nanoparticle formation
  • the surface-bonding agent it is possible to avoid parasitic side-reactions of the surface-bonding agent with the decomposition-promoting reagent by adding the surface-bonding agent after the initial decomposition of the precursor.
  • a second motivation for adding the strongly binding surface-bonding agent after the initial decomposition of the precursor is that very strong bonds between the nanoparticle and the surface-bonding agent may inhibit nanoparticle growth. Notwithstanding this point, it is possible to add the surface-bonding agent to the reaction mixture prior to, or at the same time as, the decomposition-promoting agent.
