Abstract
The influence of short-chain dithiols used in a mixture with 1-dodecanethiol to build up ZnS shells, on the spectral and luminescent properties of colloidal InP@ZnS quantum dots in the course of their liquid-phase colloidal synthesis has been studied. It has been shown that the use of dithiols permits targeted control of the luminescent properties of colloidal quantum dots. In this case, nanoparticles with a narrow emission band of ≈50 nm and a luminescence quantum yield up to 0.95 can be synthesized. The results obtained extend the capabilities of using InP@ZnS colloidal quantum dots in various functional materials.
