铕配合物-醇酸树脂复合体系的荧光性能

Luminescence Property of Eu(OC_3H_7)β_2 Complex-Alkyd Resin Composite System

合成了稀土铕配合物Eu(OC3H7)β2,并与醇酸树脂掺杂,考察不同β二酮如α-噻吩甲酰三氟丙酮(HT-TA)和二苯甲酰甲烷(HDBM)对复合体系荧光性能的影响。结果表明,掺杂配合物Eu(OC3H7)(DBM)2或Eu(DBM)3的醇酸树脂主要呈现位于460 nm附近醇酸树脂荧光发射峰;而掺杂Eu(OC3H7)(TTA)2配合物,在380 nm激发下发射很强的Eu3+离子5D0→7FJ(J=0,1,2,3,4)跃迁红色特征荧光。

The complex Eu （ OC3H7 ） β2, containing β - diketone （ i. e. trifluorothenoylacetone HTTA or dibenzoyl methane HDBM）, was synthesized and the influences of different β - diketone group on luminescence property of modified alkyd resin doping with Eu（ OC3H7 ） β2 complex were studied. The results showed that modified alkyd resin doping with Eu （ OC3 H7 ） （DBM） 2 or Eu （DBM） 3 complex exhibited luminescence at wavelength 460nm. Whereas the modified alkyd resin doping with Eu （OC3 H7 ） （TTA）2 exhibited strong characteristic luminescence of europium ion ^5 Do→ ^7 FJ （ J = 0,1,2,3,4 ） at 579、592、613、651、700nm respectively with 380nm excitation.
