Abstract

The invention discloses a preparation method of a GdF3:Yb3+ and Er3+ to upconversion fluorescence nanomaterial. The preparation method comprises the following steps that (a) anhydrous ethanol, deionized water and a thiohydracrylic acid solution are mixed; (b) Gd(NO3)3.6H2O and Yb(NO3)3.5H2O powder is weighed and put in the mixed solution, and then a Er(NO3)3.5H2O solution is added; (c) an NH4F solid is weighed and added into the mixed solution in the step (b); (d) the liquid prepared in the step (c) is transferred to a polytetrafluoroethylene hydrothermal high-pressure reaction kettle, and continuous heating is performed at high temperature; (e) after the reaction kettle is cooled to room temperature, centrifugation is performed, and a precipitate is washed with ionized water and anhydrous ethanol and is dissolved in the deionized water; (f) the solution obtained in the step (e) is centrifuged, and the white precipitate is dried. Thiohydracrylic acid is used as a surface modification agent, GdF3:Yb3+ and Er3+ to upconversion nanoparticles are synthesized by adopting a one-step hydrothermal method, the varieties of modification agents for surface modification of upconversion nanoparticles are enriched, and a theoretical and experimental basis is provided for further probe establishment and targeted delivery of anti-cancer drugs.

Description

technical field [0001] The invention relates to the field of luminescent materials, specifically a GdF 3 :Yb 3+ ,Er 3+ Preparation method of upconversion fluorescent nanomaterial. Background technique [0002] Up-conversion nanomaterials are a class of luminescent materials that can convert infrared light into visible light. Due to their great potential in optical communication, high-density optical storage, lighting and display, small solid-state lasers, infrared quantum computing detectors, and anti-counterfeiting technology, etc. The potential application prospects have attracted extensive attention. Among the numerous upconversion nanomaterials, rare earth fluoride nanomaterials have a small refractive index and low phonon energy, resulting in reduced possibility of non-radiative decay, high chemical stability and relatively low crystallization temperature, etc. Advantages, and is considered to be one of the best up-conversion luminescent host materials. Rare-earth ...
