Abstract

The invention relates to a preparation method of boron oxide quantum dots, and belongs to the technical field of quantum dot preparation. The method comprises the following steps: dissolving ammoniumpentaborate and boric acid in deionized water, uniformly stirring the mixture to obtain an ammonium pentaborate / boric acid mixed solution, carrying out hydrothermal reaction to obtain an initial product solution, adding a reducing agent solution, fully stirring the solution, and carrying out freeze drying to finally obtain the boron oxide quantum dot powder. The preparation method is simple, conditions are mild, no harmful by-product is generated in the preparation process, and is environmentally friendly; by optimizing the precursor, the structure of the material is controllable, and therefore, the obtained boron oxide quantum dot is uniform in size, has blue fluorescence, can be used as a boron-containing drug for boron neutron capture therapy, and has large-scale production potential and wide commercial application prospect.

Description

technical field

[0001] The invention belongs to the technical field of quantum dot preparation, and in particular relates to a preparation method and application of boron oxide quantum dots. Background technique

[0002] Boron quantum dots are a new type of boron nanomaterials, especially in the fields of chemical sensors, bioimaging, nanomedicine, solar cells, light-emitting diodes (LEDs), electrocatalysis, neutron capture therapy, and new energy. , and has potential application value in the fields of biology, medicine, energy storage devices, and new semiconductor devices.

[0003] The current methods for preparing quantum dots are divided into top-down and bottom-up methods. In the top-down process, macromolecules are destroyed or dispersed into small-sized quantum dots by physical or chemical methods; The bottom-up approach mainly aggregates and carbonizes a series of small molecules into quantum dots through chemical reactions. The top-down method mainly focuses on va...
