Abstract

The invention discloses a dysprosium-contained fluorescent crystal, which relates to a compound [Dy(L)3(H2O)2]n 6nH2O, wherein L refers to 2-pyrazinemonocarboxylic acid. The compound is prepared by adopting a solvent thermal reaction method, i.e. the compound is synthetized through heating Dy(Ac)3 4H2O and the 2-pyrazinemonocarboxylic acid after distilled water is added, and simultaneously, a monocrystal is prepared. The compound can be applied to manufacturing fluorescent materials.

Description

Technical field [0001] The patent of the present invention relates to a dysprosium-containing fluorescent crystal [Dy(L) 3 (H 2 O) 2 ] n 6nH 2 O (wherein L is 2-pyrazinecarboxylic acid). Background technique [0002] The degree of development of the three major industries of materials, information and energy has been recognized as an important indicator of a country's comprehensive national strength, and materials are the material basis of the information and energy industries. The production of every important new material is a milestone in the development process of human society. One of the most important research fields of this century is the development of new materials. As an important material, rare earth fluorescent materials play an extremely important role in the field of contemporary luminescent materials and bioluminescent probes. [0003] In general, rare earths emit strong fluorescence when the f-f charge transition occurs. However, the absorption coeff...
