The core semiconductor material is provided on the molecular cluster compound.
Claims14
A nanoparticle comprising:
- (i) a molecular cluster compound incorporating ions from groups 12 and 16 of the periodic table, and
- (ii) a core semiconductor material provided on said molecular cluster compound,
- wherein the core semiconductor material incorporates ions from groups 13 and 15 of the periodic table.
A method of producing nanoparticles, the method comprising the steps of:
- providing a nanoparticle precursor composition comprising group 13 ions and group 15 ions;
- and
- effecting conversion of the nanoparticle precursor into nanoparticles,
- wherein said conversion is effected in the presence of a molecular cluster compound incorporating group 12 ions and group 16 ions under conditions permitting nanoparticle seeding and growth.
