Abstract
Shaped nanocrystal particles and methods for making shaped nanocrystal particles are disclosed. One embodiment includes a method for forming a branched, nanocrystal particle. It includes (a) forming a core having a first crystal structure in a solution, (b) forming a first arm extending from the core having a second crystal structure in the solution, and (c) forming a second arm extending from the core having the second crystal structure in the solution.
Claims29
A process of forming a nanocrystal particle, the process comprising:
- (a) providing a core having a first crystal structure in a solution;
- and
- (b) forming an arm extending from the core having a second crystal structure in the solution.
A process for forming semiconductor nanocrystal particles comprising:
- introducing semiconductor nanocrystal particle precursors into a heated mixture of surfactants capable of promoting the growth of tetrapod shaped semiconductor nanocrystal particles;
- and
- forming tetrapod shaped semiconductor nanocrystal particles.
A process for forming shaped nanocrystal particles comprising:
- (a) mixing semiconductor precursors and a mixture of surfactants to form a solution;
- and
- (b) forming nanocrystal particles in the solution,
- wherein the nanocrystal particles are in the form of teardrops or arrows.
