Abstract

The invention belongs to the field of preparation of multifunctional nanomaterials, and particularly relates to a preparation method of a Eu-doped YBO3 nano tube bundle material. A YBO3: Eu nano tubebundle prepared with a hydro-thermal synthesis method is provided, and the method comprises specific steps that a borate solution is obtained after yttrium salt, europium salt and boric acid are mixed, an alkaline agent and a surfactant are added to the borate solution, the hydro-thermal synthesis reaction is performed, and the YBO3: Eu nano tube bundle is prepared. The preparation method is simple and environmentally friendly, addition of templates is not needed, and the prepared YBO3: Eu nano tube bundle material has a smaller size and the tubular characteristic.

Description

technical field [0001] The disclosure belongs to the field of preparation of multifunctional nanomaterials, in particular to a europium-doped yttrium borate (YBO 3 :Eu) Low-dimensional nanotube bundle material and preparation method. Background technique [0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] Low-dimensional nanomaterials have at least one dimension in the nanoscale in three-dimensional space, including zero-dimensional quantum dots; one-dimensional nanotubes, nanowires, nanobelts and two-dimensional nanotubes, etc., due to their excellent properties and applications in different fields have been extensively studied.
