摘要
利用DV-Xa方法分别计算了和原子簇的能态密度和能级,在能级图的基础上,给出了05~0.9μm(1.6eV^2.3eV)范围内Bi-YIG的与光吸收有关的跃迁能级、振子强度和跃迁线宽,并计算了相应的吸收谱。
On the basis of density of states and valence orbital energy diagrams of Fe3+O2-6 cluster and Fe3+O2-4 cluster which are calculated by DV-Xα method, the transition energies, transition linewidths and oscillator strengths are given for Bi-YIG in the wavelength from 0.5 to 0.9μm. The optical absorption spectra of Bi-YIG are calculated. The results are consistent with experimental data.
