a、激发光谱(excitation spectrum) b、发射光谱(emission spectrum) 硫酸奎宁的激发光谱(a)和发射光谱(b) (5)荧光光谱的特点a、斯托克斯位移(Stocks shift):荧光发射波长总是大于激发光波长。原因:激发态分子由于内部能量转换和振动驰豫过程而迅速到达S1*电子态的最低振动能级,从而存在着无辐射能量损失。b、荧光发射...
X光电子能谱(X-ray photoelectron spectroscopy(XPS))是一种表面灵敏的定量分析手段,尽管理论上说是能定量分析,但是其作为定性分析的功能其实更加出众,因为得到XPS能谱后还要对数据进行拟合,而数据和拟合的好坏会导致得到的分析结果差很多,所以XPS一般还需要别的仪器辅助表征。XPS能够快速分析出样品中的元素类型,但是元...
Density Functional Theory (DFT) calculations of the temperature effects on the X-ray emission spectra of nickel and copper were done using the linearized augmented plane-wave elk code (elk.sourceforge.net). The effect of thermal expansion on the emission spectrum was simulated by expanding the ro...
