研究了在层间作用和电场作用下球状纳米系统的电子能量和波函数.以CdS/HgS/CdS球状纳米系统为例,讨论了层间作用、电场和样品线度对高能级斯塔克效应以及谱线频率和强度的影响.结果表明:CdS/HgS/CdS球状纳米系统在外电场作用下发生斯塔克效应的能级分裂规律与氢原子类似,但能级位移量不同.谱线频移与电场强度的平方成正比,多数谱线的频移随线度增大而减小,少数谱线的频移则相反;而层间作用引起谱线的频移随线度增大而减小.除少数谱线外,多数谱线的相对强度随线度增大而减小,层间作用不会改变相对强度随线度的变化趋势,但要改变谱线的强度值,线度较小时层间作用对谱线强度的影响才显著.
The electron energy and the wave function of a spherical nanosystem under interlayer interaction and electric field are investigated. Taking the CdS / HgS / CdS spherical nanosystem as an example, the effects of interlayer interaction, electric field and sample linearity on high energy Stark effect As well as the effect of spectral line frequency and intensity.The results show that the energy level splitting of the CdS / HgS / CdS spherical nanosystems under the action of an external electric field is similar to that of hydrogen atoms, but the energy level shifts are different. Proportional to the square of the electric field strength, the frequency shift of most spectral lines decreases with the increase of linearity, while the frequency shift of minority lines reverses. However, the frequency shift of spectral lines caused by interlayer interaction decreases with the increase of linearity Except for minority lines, the relative intensities of most of the lines decrease with the increase of linearity, and the interaction between layers does not change the trend of relative intensity with linearity, but to change the intensity value of the line, The effect of interlayer interaction on spectral line intensity is significant.
