Abstract
A quantum dot may include a core including indium (In) and A1, and a first shell covering the core, wherein A1 may be a group III element other than indium, a ratio of a radius of the core to a thickness of the first shell may be in a range of about 1:1 to about 9:1, and the quantum dot may emit blue light having a maximum emission wavelength in a range of about 440 nanometers (nm) to about 480 nm.
Claims20
A quantum dot comprising:
- a core comprising indium (In) and A1;
- and
- a first shell covering the core,
- wherein
- A1 is a group III element other than indium,
- a ratio of a radius of the core to a thickness of the first shell is in a range of about 1:1 to about 9:1, and

4 more elements
A method of preparing quantum dots, the method comprising:
- mixing a first precursor comprising indium (In) with a second precursor comprising A1 to prepare a core;
- and
- mixing a third precursor comprising A3 with a fourth precursor comprising B2 to prepare a first shell,
- wherein A1 is a group III element other than indium, A3 is a group III element, B2 is a group VI element, and a molar ratio of the second precursor to the third precursor is 1:5.2 or greater.
