Abstract
A nanocrystal with a large Stokes shift includes a matrix domain having a composition of M1xM2yAz, and a plurality of seed domains which are distributed in the matrix domain and each of which has a composition of M1x′M2y′Az′, wherein M1, M2, A, x, y, z, x′, y′, and z′ are as defined herein.
Claims15
A nanocrystal, comprising:
- a matrix domain having a composition of M1xM2yAz;

- a plurality of seed domains which are distributed in said matrix domain and each of which has a composition of M1x′M2y′Az′,
- wherein
- M1 is,
- M2 is,
- A is S, x, y, and z are respectively a number of M1, a number of M2, and a number of A to satisfy valence requirement of said composition of M1xM2yAz,
- x′, y′, and z′ are respectively a number of M1, a number of M2, and a number of A to satisfy valence requirement of said composition of M1x′M2y′Az′,
- y is in a range larger than 0 and less than 1,
- y′ is in a range from 0 to less than 1 and is less than y,
- a sum of x and y is 1, and
- a sum of x′ and y′ is 1.
