Embodiment 1
[0029] Example 1 Preparation of multifunctional rare earth complex
[0030] The specific synthesis method is as follows: dysprosiumnitrate hexahydrate (0.043 g, 0.10 mmol), 3,5-bis(2-pyridine)-1,2,4-triazole (0.023 g, 0.10 mmol) and triethyl Amine (0.020 g, 0.2 mmol) was sequentially added to a Teflon-lined stainless steel reaction kettle containing 8 ml of methanol, sealed and airtight. After heating at 120 degrees for 72 hours, it was naturally cooled to room temperature to obtain colorless crystals. The rate is about 32%.
Embodiment 2
[0031] Example 2 Determination of product structure
[0043] Example 3: At 300 K, taking 200 mg of the product obtained in Example 1 under the action of an alternating electric field of 1500 V and 200 Hz, the obtained saturation polarization was 0.16 μC·cm ?2 , the remanent polarization is 0.10 μC cm ?2 , the result is image 3 shown.

Abstract
The invention provides a multifunctional rare-earth complex, a preparation method thereof and application of the complex in a white light LED (Light Emitting Diode), a ferroelectric and a monomolecular magnet. The chemical molecular formula of obtained dihydroxyl.tetranitro.tetra(3,5-di(2-pyridine)-1,2,4-triazole).dimethoxy tetra-dysprosium (III) is Dy4(bpt)4(NO3)4(OH)2(OCH3)2.3CH3OH. The multifunctional rare-earth complex provided by the invention can be used for emitting obvious white light at room temperature and normal pressure under exciting light of 210-310 nanometers and transforming a color coordinate CIE from (0.300, 0.310) to (0.308, 0.322), shows the ferroelectric behavior at room temperature and normal pressure under the action of an alternating electric field at 100-1500 V and 200 Hz, achieves the maximal polarization intensity of 0.16 muC.cm<-2> during 1500 V, shows the monomolecular magnet behavior at low temperature in zero external field under the action of an AC (Alternating Current) magnetic field at 1-1488 Hz and achieves the characteristic relaxation time of 2.91*10<-7> s and the effective energy barrier of 115.51 K.
Description
technical field [0001] The invention relates to the application technology field of dysprosium, and more particularly, to a multifunctional rare earth complex photoelectromagnetic material and its application. Background technique [0002] Multifunctional opto-electromagnetic materials refer to functional materials with two or more functions of light, electricity, magnetism, heat, sound, mechanics, etc. At present, complex multifunctional materials with optical, electrical and magnetic properties are a hot spot in the research of new materials. White LEDs are also a promising type of optical lighting materials. Ferroelectric materials are one of pyroelectric materials with broad application prospects. Single-molecule magnets exhibit unique properties at low temperatures and become one of the most promising materials in the field of magnetics. A research hotspot that has received much attention. [0003] White LEDs have very promising application prospects in lighting a...
