Abstract: A process for producing nanoparticles incorporating ions selected from groups 13, 16, and 11 or 12 of the periodic table, and materials produced by the process. In an embodiment, the process includes effecting conversion of a nanoparticle precursor composition comprising group 13, 16, and 11 or 12 ions to the material of the nanoparticles in the presence of a selenol compound. Other embodiments include a process for fabricating a thin film including nanoparticles incorporating ions selected from groups 13, 16, and 11 or 12 of the periodic table as well as a process for producing a printable ink formulation including the nanoparticles.
Abstract: Method for producing a nanoparticle comprised of core, first shell and second shell semiconductor materials. Effecting conversion of a core precursor composition comprising separate first and second precursor species to the core material and then depositing said first and second shells. The conversion is effected in the presence of a molecular cluster compound under conditions permitting seeding and growth of the nanoparticle core. Core/multishell nanoparticles in which at least two of the core, first shell and second shell materials incorporate ions from groups 12 and 15, 14 and 16, or 11, 13 and 16 of the periodic table. Core/multishell nanoparticles in which the second shell material incorporates at least two different group 12 ions and group 16 ions. Core/multishell nanoparticles in which at least one of the core, first and second semiconductor materials incorporates group 11, 13 and 16 ions and the other semiconductor material does not incorporate group 11, 13 and 16 ions.

Abstract: A method of producing nanoparticles comprises effecting conversion of a nanoparticle precursor composition to the material of the nanoparticles. The precursor composition comprises a first precursor species containing a first ion to be incorporated into the growing nanoparticles and a separate second precursor species containing a second ion to be incorporated into the growing nanoparticles. The conversion is effected in the presence of a molecular cluster compound under conditions permitting seeding and growth of the nanoparticles.
