Study on elemental speciation in airborne particulate matter by XANES;

用X射线吸收近边结构谱研究大气颗粒物中元素的种态

Valences of rare earth ions in long afterglow silicate phosphors were studies by L3 edge X-ray absorption near edge structure ( XANES ) spectroscopy.

利用同步辐射X射线吸收近边结构(XANES)对Eu,Dy共掺杂硅酸盐体系长余辉发光材料中的稀土离子的价态进行分析,结果表明有+2价和+3价的Eu离子存在,但未发现+1价的Eu离子,而Dy离子则始终以+3价形式存在,未发现+4价Dy离子存在。

The Eu-L3 edge XANES and luminescent spectra of CaBPO5:Eu, SrB4O7:Eu and Ba3(PO4)2:Eu prepared by solid state reaction at high temperature in air were determined.

测定了采用高温固相反应在空气条件下合成的发光体CaBPO_5:Eu、SrB_4O_7:Eu和Ba_3(PO_4)_2:Eu的Eu-L_3边的X射线吸收近边结构(XANS)谱和发光光谱。

The carbon K near edge X-ray absorption fine structure(NEXAFS)spectra of polythiophene derivatives electrochemically polymerized on a flat Pt electrode were recorded using linearly polarized soft X-ray synchrotron radiation.

采用电化学方法将噻吩衍生物[3-(2-甲氧基苯)噻吩和3-溴代噻吩]聚合沉积到Pt片上,利用同步辐射光源采集聚噻吩衍生物中C的近边X射线吸收精细结构(NEXAFS)谱,以特征吸收峰强度对光的入射角度的依赖性为判据,实验证明了聚噻吩衍生物分子在金属表面的分子取向。
