Abstract

The disclosed preparation method for a high-efficient green-light rare-earth compound film comprises: (1) preparing any one rare-earth terbium (III) compound of Tb(acac)3Phen, Tb(TFA)3Phen, Tb(HFA)3Phen and Tb(TTA)3Phen (acac, TFA, HFA, TTA, and Phen for acetylacetone, trifluoro acetylacetone, hexafluoro acetylacetone, thenoyl trifluoroacetone, and 1, 10-ortho-phenanthroline, respectively); (2) preparing functional aqueous phase, mixing the terbium (III) compound with one fatty acid for ultrathin film preparation on gas-liquid two-dimensional surface and the transfer toward hydrophobic solid substrate. This product has characteristic fluorescence-emission peak on 535.0-557.5nm, keeps layer periodic structure after 26 weeks to detect out the fluorescent signal, and shows important application.

Description

technical field

[0001] The invention relates to a method for preparing a rare earth compound thin film luminescent material, in particular to a method for preparing an atypical amphiphilic terbium (III) compound thin film without hydrophobic hydrocarbon chains by using molecular level assembly technology. Background technique

[0002] In terms of preparation of characteristic materials, the preparation of ultra-thin films of rare earth compounds by the assembly technology at the molecular level - Langmuir-Blodgett (LB) membrane technology has become a research hotspot and a key topic for scientific and technological workers at home and abroad in recent years. my country's research level in this field ranks among the top in the world and has produced a large number of innovative results. However, because the traditional LB membrane technology requires the molecules in the membrane to be amphiphilic molecular systems containing hydrophobic long alkane chains, and many function...
