摘要

Radiation rates and emission quantum yields of Eu(III) were modified using asymmetric deuterated Eu(III) complexes doped in poly (methyl methacylate) (PMMA) deuterated tris-(hexafluoroacetylacetonato) europium-(III) with phospine oxide in order to produce lowthreshold levels for laser transmission and amplifier emissions. Geometric structures of asymmetric Eu(III) complexes were determined by single-crystal X-ray diffraction and Judd-Ofelt analysis. Luminescent polymers were fabricated by incorporating Eu(III) complexes in a PMMA matrix. Luminescent PMMA containing Eu(hfa-D)_3(DPFBPO)_2 exhibited the highest quantum yield and fastest radiation rate (quantum yield = 78 ± 6%, radiation rate = 1.2 * 10~3 s~(-1)) of the PMMA matrixes. Emission quantum yields of Eu(hfa-D)_3 (TPPO)_2 in acetone-d_6 were found to be > 95%. This radiation rate is of the same order as values reported for Nd:YAG. Prepared luminescent polymers including Eu(hfa-D)_3-(TPPO-F)_2 showed promising results for applications to novel organic Eu(III) devices, such as organic liquid lasers, plastic lasers, and optical fibers.
