Abstract

The invention discloses a method for preparing a narrow-band ytterbium-thulium double-doped GZO nanometer fluorescent material and relates to a method for preparing a GZO nanometer fluorescent material. The invention aims at solving the problems that the conventional up-conversion blue-light substrate material is wide in wave band distribution and large in particle size and is unfavorable for applications in aspects such as medicines, biology and radar. The preparation method comprises the following steps: mixing NaOH solution and Zn(NO3)3 solution, dripping Ga(NO3)3 solution, adding ytterbium oxide nitric acid solution and thulium oxide nitric acid solution, and carrying out a hydrothermal reaction, thereby obtaining the narrow-band ytterbium-thulium double-doped GZO nanometer fluorescent material. The narrow-band ytterbium-thulium double-doped GZO nanometer fluorescent material prepared by the method disclosed by the invention is narrow in wave band distribution, and up-conversion blue light in the narrow band is obtained. The size of the prepared narrow-band ytterbium-thulium double-doped GZO nanometer fluorescent material is 40-50nm, and the morphology of the fluorescent material is a nanorod. According to the method disclosed by the invention, the narrow-band ytterbium-thulium double-doped GZO nanometer fluorescent material can be obtained.

Description

technical field [0001] The invention relates to a preparation method of a GZO nano fluorescent material. Background technique [0002] In the field of optics, up-conversion is the conversion of long-wavelength light into short-wavelength light. The so-called up-conversion luminescence refers to the phenomenon of converting two or more low-energy photons into one high-energy photon, generally referring to the conversion of infrared light into visible light, and its luminescence mechanism is based on a two-photon or multi-photon process. Up-conversion luminescent materials have many excellent properties and wide applications, for example, they can be used to realize simple, cheap and reliable compact laser systems. However, the currently reported upconversion blue light matrix materials have relatively wide wavelength distribution and large particle size, which have limitations in biomedical applications. In order to solve this problem, the present invention prepares an up-c...
