Abstract

In one embodiment, the invention discloses a tetrathiomolybdate radical / 1-octane sulfonate radical / LEuH complex, of which the chemical formula is Eu(OH)<2.41>(C8H17O3S)<x>(MoS4)<y>(NO3)<0.02>.<z>H2O. When the complex is dispersed in a stripping solvent composed of water and formamide to form a colloidal nano-sheet suspension liquid, the fluorescent emission intensity of the suspension liquid is significantly higher than that of a colloidal nano-sheet suspension liquid that is formed by dispersing a 1-octane sulfonate radical / LEuH complex in the same stripping solvent. In addition, by using water to replacing a part of formamide in the stripping solvent, the complex is more environment-friendly and has a better application prospect.

Description

technical field [0001] The invention relates to the field of organic synthesis, in particular to a tetrathiomolybdate / 1-octanesulfonate / LEuH complex and a synthesis method thereof. Background technique [0002] Layered rare-earth hydroxides (Layered Rare-earth Hydroxides, LRH) are a new type of layered anionic materials. The structure and properties of organic or inorganic anions are obtained to obtain multifunctional layered composite materials with laminate properties and interlayer anion properties. Among the many rare earth ions, Eu 3+ It can emit a characteristic red spectrum in the visible light region, therefore, layered europium hydroxide (abbreviated as LEuH) can be used to prepare luminescent materials. However, layered europium hydroxide is difficult to be stripped in a solvent (also called stripping solvent), so it is difficult to be used in the preparation of thin-film light-emitting materials. Studies have shown that intercalation of surfactant 1-octane sulf...
