Abstract:
Disclosed herein is a multilayer nanocrystal structure comprising a nanocrystal alloy core comprising two or more nanocrystals and including an alloy interlayer formed at an interface between the two or more nanocrystals, and one or more layers of nanocrystal shells formed sequentially on the surface of the nanocrystal alloy core, wherein the nanocrystal shells each have different band gaps. The multilayer nanocrystal structure can be applied to various electronic devices owing to its advantages of high luminescence efficiency, superior optical stability, and superior chemical stability.

Claim (Index 1):
A multilayer nanocrystal structure comprising:\n (a) a nanocrystal alloy core comprising two or more nanocrystal layers and including an alloy interlayer formed at an interface between the two or more nanocrystal layers and comprising a compositional gradient of two or more materials present at the interface of the two or more nanocrystal layers, wherein the compositional gradient ranges from 100% of a first nanocrystal material present at the interface of the interlayer with a first nanocrystal layer to 100% of a second nanocrystal material present at the interface of the interlayer with a second nanocrystal layer, wherein the first nanocrystal material and the second nanocrystal material are different from each other in terms of elemental compositions and the alloy interlayer is formed at between the first nanocrystal and the second nanocrystal and wherein the first nanocrystal material comprises CdS, CdSe, CdTe, ZnTe, ZnSe, HgS, HgSe, HgTe, PbS, PbSe, PbTe, AlN, AlP, AlAs, GaN, GaP, GaAs, InN, InP, InAs, or a mixture thereof and the second nanocrystal material comprises ZnS, ZnSe, or a combination thereof; (b) one or more layers of nanocrystal shells, each having different band gaps, sequentially grown on a surface of the nanocrystal alloy core to form the nanocrystal shells such that a first layer of the nanocrystal shells covers the exposed surface of the nanocrystal alloy core, and each additional layer of the nanocrystal shells covers an exposed surface of a previous layer of the nanocrystal shells; and (c) an organic material coordinated to the surface of the nanocrystal shells, wherein the nanocrystal shells are selected from the group consisting of Group II-VI, Group III-V, Group IV-VI compounds, and mixtures thereof; wherein the outermost shell of the nanocrystal shells has a band gap larger than a band gap of the nanocrystal alloy core, and an inner shell layer has a smaller energy band gap compared to the nanocrystal alloy core, and wherein the organic material is selected from the group consisting of C 6-24  alkanes and C 6-24  alkenes each having a terminal carboxylic acid \u2014COOH) functional group, C 6-24  alkanes and C 6-24  alkenes each having a terminal phosphoric acid (\u2014PO(OH) 2 ) functional group, C 6-24  alkanes and C 6-24  alkenes each having a terminal sulfhydryl (\u2014SH) functional group, C 6-24  alkanes and C 6-24  alkenes each having a terminal sulfinic acid (\u2014SOOH) functional group, C 6-24  alkanes and C 6-24  alkenes each having a terminal sulfonic acid (\u2014SO 3 H) functional group, and C 6-24  alkanes and C 6-24  alkenes each having a terminal amine (\u2014NH 2 ) group.
