| abstract |
A nanoparticle comprising a core comprised of a first material and a layer comprised of a second material. 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. Methods for preparing such nanoparticle are also described. There is further provided a nanoparticle comprising a core comprised of a first material and a layer comprised of a second material deposited on said core, wherein 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. |
