The UV absorption and photoluminescence properties of phenanthroline derivatives with triphenylamine and oxadiazole groups and their europium complexes were investigated. These europium complexes display intense UV absorption and photoluminescence properties. The PL results from emission of Eu3+ ion in their pure thin films. A maximum PL wavelength is 612 nm and a full width at half maximum is from 9 nm to 15 nm for the PL of these europium complexes, respectively.

2研究了三芳胺和噁二唑功能化的邻菲罗啉中性配体及其铕配合物的紫外吸收和光致发光性能，研究结果表明，这类新型的铕配合物具有强烈的紫外吸收和光致发光性能，铕配合物在固体薄膜状态下都能发射出强烈的铕离子特征峰，其最大发射波长为612 nm，半峰宽为9～15 nm。

Here we introduced oxadiazole moiety to theside-chain of Ph-PPV to enhance the electron transport properties. The luminescenceefficiency and luminescence brightness (1.33cd/A, 9400 cd/m~2) of the Ph-PPV withside oxadiazole moiety are much higher than non-oxadiazole Ph-PPV (0.70 cd/A,2300 cd/m~2), and these polymers emitted green light which unaffected by theintroduction of oxadiazole moiety. Anthracene has a rigidity and planar structure which shows high photoluminescenceand thermo-stability.

Visual carbon stars whose mid-infrared spectra are mainly dominated by photospheric continuum and show large excesses at 60um, represent a transition phase which follows an interruption of mass loss from the oxygen-rich phase and begins a new phase of the mass loss of carbon-rich material. Excesses at 60um in these stars are the emission from the residual of oxygen-rich material.
