Embodiment 1

[0019] Weigh 0.03 grams of Eu(TTA)3Phen complex solid powder and dissolve it in 2.5 milliliters of acetone, add the above solution to 50 milliliters of n-propanol, stir and mix evenly at 2°C, and gradually precipitate the rare earth complex nanoparticles, The mixed solution turns into a gray complex nano sol, and the sol is vacuum-dried at 30°C to obtain Eu(TTA)3Phen complex nanoparticles with a particle diameter of about 70 nm. (TEM photo see figure 1 )

Embodiment 2

[0021] Weigh 0.03 grams of Eu(TTA)3Phen complex solid powder and dissolve it in 2.5 milliliters of acetone, add the above solution to 100 milliliters of n-propanol, stir and mix evenly at 25°C, and gradually precipitate out the rare earth complex nanoparticles, The mixed solution turns into a gray rare earth complex nano sol, and the sol is vacuum-dried at 60° C. to obtain Eu(TTA)3Phen complex nanoparticles with a particle diameter of about 100 nm. (TEM photo see figure 2 and Figure 4 )

Embodiment 3

[0023] Weigh 0.06 g of Eu(TTA)3Phen complex solid powder and dissolve it in 5.0 ml of acetone, add the above solution into 50 ml of n-propanol, stir and mix at 58°C, with the gradual precipitation of rare earth rare earth complex nanoparticles , the mixed solution becomes a gray rare earth complex nano sol, and the sol is vacuum-dried at 130° C. to obtain Eu(TTA) 3Phen complex nanoparticles with a particle diameter of about 150 nm. (TEM photo see image 3 )

Abstract

A process for preparing the RE matches nanoparticles includes such steps as dissolving RE matches in proper solvent, adding the solution to the solvent difficult to dissolve RE matches in it, stirring, redepositing to educe out nanoparticles and obtain nano-sol of RE matches, and drying.

Description

technical field [0001] The invention relates to nanomaterials in the field of inorganic chemical industry, in particular to a method for preparing rare earth complex nanoparticles. Background technique [0002] Yttrium and lanthanides are collectively called rare earth elements. Since the 1960s, the synthesis, structural analysis and application research of rare earth complexes have been extensively and deeply carried out. Rare earth complexes can be used as materials such as luminescence, magnetism, catalysis, gas sensing, superconductivity, etc., and are widely used in many fields of industrial production and scientific research. [0003] Nanomaterials, which emerged in the 1980s, refer to new materials whose constituent phases or grains are controlled at the nanometer scale. Nanomaterials have the characteristics of small size, large surface, and multiple interfaces, and present novel effects different from conventional materials. Therefore, they have attracted widesprea...
