CORE/SHELL NANOCRYSTALS AND METHOD FOR PREPARING THE SAME

摘要

A core/shell nano-crystalline is provided to have an excellent luminous efficiency and an excellent crystalline at the same time and to be synthesized easily by adjusting a form and a size of the nano-crystalline and to have a structure including the shell nano-crystalline in which metal is doped on a surface. A core/shell nano-crystalline comprises (a) a core nano-crystalline and (b) a shell nano-crystalline which is formed on the core nano-crystalline and is doped to metals. A material comprising the core nano-crystalline is 12 group-16 group, 13 group-15 group and 14 group-16 group compounds and a mixture thereof. A material comprising the core nano-crystalline is selected from a group consisting of CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, HgS, HgSe, HgTe, PbS, PbSe, PbTe, AlN, AlP, AlAs, GaN, GaP, GaAs, InN, InP, InAs and a mixture thereof.
