Afterwards, using the spherical tensor form of many-electron atom Hamilton and the irreducible tensor theory, the relativistic and fine-structure energy correction to the non-relativistic energy of Boron-like atoms in the ground and the first excited states have been further investigated. A theoretically analytic way has been given as to the calculation of all the radial integrations and spin summations, which concern interactions such as orbit-orbit, spin-orbit, spin-spin and spin-other-orbit. Therefore, the whole process of calculating the many- electron atom energy structures has been explicitly revealed and the results are relatively precise and satisfactory.

XRD showed hexagonal wurtzite structure. Room-temperature PL spectra of perfectly overcoated CdSe/ZnS only showed a narrow band edge emission. Emission peak was great red-shifted relative to absorption and the shift increases as the size decreases. The size-dependence of shift could be explained very well in terms of excition fine-structure model and stress at interface owing to lattice mismatch contributes to the shift between CdSe and CdSe/ZnS with the same size.

结果显示表面修饰完善的样品的荧光光谱只有一个窄而强的带边发射;所有样品的荧光峰相对于1S-1S吸收峰有较大的红移,并且移动量随尺寸的减小而增加,利用激子的精细结构模型很好地解释了红移量和尺寸的关系;核/壳结构的样品的吸收峰和荧光峰相对于同尺寸的单量子点也有红移现象,这是由于CdSe和ZnS的晶格失配在界面上产生压力造成的。

The relationship between the microstructure and the electrochemical surface characteristics of the oxide anodes was explained.

Treatment by different methods, samples in original state, free of wax, free of lignin and hemicellulose were obtained. Then, they were attached on the surface of new cleaved mica and measured by tapping mode AFM. It was found that the main structure of straw cell wall is composed of buddles of cellulose microfibrils, and hemicellulose links them together to form a network structure, on the surface of the network lignin aggregate together to form a protect level. The AFM result consistency very well to the theoretical model of cell wall proposed by Vincent.
