Publication number: 20170218268Abstract: Nanoparticles include or consist essentially of (i) a core that itself includes or consists essentially of a first material, and (ii) a layer including or consisting essentially of a second material. In various embodiments, one of the first and second materials is a semiconductor material incorporating ions from group 13 and group 15 of the periodic table, and the other of the first and second materials is a metal oxide material incorporating metal ions selected from any one of groups 1 to 12, 14 and 15 of the periodic table. In other embodiments, one of the first and second materials is a semiconductor material, and the other of the first and second materials is an oxide of a metal selected from any one of groups 3 to 10 of the periodic table. Methods for preparing such nanoparticles are also described.Type: ApplicationFiled: April 13, 2017Publication date: August 3, 2017Inventors: Nigel Pickett, Steven Daniels, Imrana Mushtaq

Publication number: 20140155640Abstract: The present invention relates to a process for the production of surface functionalised nanoparticles, such as the production of semiconductor quantum dot nanoparticles incorporating surface-bound functional groups which increase the ease with which the dots can be employed in applications, such as incorporation into solvents, inks, polymers, glasses, metals, electronic materials and devices, bio-molecules and cells. The method comprises reacting first and second nanoparticle precursor species in the presence of a nanoparticle surface binding ligand X—Y—Z wherein X is a nanoparticle surface binding group, Y is a linker group, and Z is a functional group, in which Y comprises a polyethyleneglycol group and/or Z comprises an aliphatic group incorporating a terminal unsaturated group, said reaction being effected under conditions permitting binding of said surface binding ligand to the growing nanoparticles to produce said surface functionalised nanoparticles.Type: ApplicationFiled: November 19, 2013Publication date: June 5, 2014Applicant: NANOCO TECHNOLOGIES LTD.Inventors: Nigel Pickett, Mark C. McCairn, Steven M. Daniels, Imrana Mushtaq, Paul Glarvey
