Abstract(in English) The novel Eu (III) complexes with bis-phosphine which have narrowed emission band (full width at half maximum=2.1nm) and large Stimulated emission cross-section (1.80×10^<-20>cm^2), was synthesized. Geometric structures of novel Eu (III) complexes were determined by single-crystal X-ray diffraction. The emission from the edge of the polymer thin films decayed following single-exponential kinetics (τ=650μs). While the emission decays at high excitation energy given >0.1mJ consisted of normal component (τ=650μs) and a faster component (τ=83μs). The ratio of the faster component increased with increasing excitation energy. These observations indicate that the faster component is due to amplified spontaneous emission (ASE). The threshold level for the ASE was estimated to be<0.05mJ.
