| titleOfInvention | Ga-doped InP quantum dot with core-shell structure and preparation method thereof |
| abstract | The invention provides a Ga-doped InP quantum dot with a core-shell structure and a preparation method thereof. The quantum dot comprises an InP nanocrystal core, a Ga-doped InGaP nanocrystal middle layer and a shell layer, wherein the Ga-doped InGaP nanocrystal middle layer consists of In x Ga y P, shell layer is ZnSe z S 1‑z Wherein x/y is more than or equal to 1 and less than or equal to 9, and z is more than or equal to 0 and less than or equal to 1. The fluorescence emission wavelength of the quantum dot is continuously adjustable within 610-780nm, the particle size is uniform, and the half-peak width of the emission peak is obviously smaller than that of a pure InP quantum dot with the same wavelength. In the present invention, pH is used 3 The Ga-doped InGaP nanocrystalline intermediate layer is a phosphorus source and is formed between the nanocrystal core and the shell, so that the defects of InP quantum dots caused by lattice mismatch are relieved, and the Ga-doped InGaP nanocrystalline intermediate layer has the characteristics of low cost, environmental protection and simplicity in operation, and can be widely applied to the fields of illumination, display and the like. |
