Abstract
Quantum dots are semiconductor nanocrystals that are a few nanometers in size that have different optical and electrical properties depending on size and shape. Some applications that quantum dots are used for, include, lasers, quantum computing, and solar cells. The goal of the research was to fuse cadmium selenide, cadmium sulfide (CdSe/CdS) core shells into dimers to increase the communication between particles in these applications. The CdSe were synthesized to 3 nm cores. Various procedures were used for CdSe/CdS synthesis, but the best performing sample contained 5 nm particles in diameter and a promising size for fusion. A metal salt for the fusion of the core shells was used to form core shell dimers. Partial coalescence to synthesize fused core shell dimers was successful with a high yield of fused particles in the solution.
Keywords: nanocrystals, CdSe/CdS, partial coalescence, high yield, fused particles
