AI Technical Summary
Existing technologies cannot effectively control the size distribution and morphology of ZnTe quantum dots, resulting in poor synthesis reproducibility and failing to meet the requirements for optical bandgap control in the blue-green light range.
Using highly reactive aminophosphorus as an anionic ligand, the size distribution of ZnTe quantum dots was controlled by a one-step high-temperature thermal injection method and a secondary growth method. The aminophosphorus was used to enhance the reactivity of tellurium ions, and the reactivity of tellurium and zinc precursors was reduced by gradient, thus realizing the preparation of monodisperse ZnTe quantum dots of different sizes.
High-quality ZnTe quantum dots with uniform size and tunable particle size were successfully prepared, solving the problems of uneven size distribution and poor synthesis reproducibility, and expanding the optical bandgap control capability of ZnTe quantum dots in the blue-green light range.
