在4K,77K,用远红外吸收光谱鉴别了氧化钇(Y_2O_3)的 C_和 C_2格点中大多数正三价镧系离子基簇光声子和 StarK 分裂分量的能量,也报导了电子 Raman 光谱,通过它能鉴别低能激发簇的分量,以系统的方式,用 C_3~i对称的晶场哈密尔顿算符法分析了由数据构成的能级示意图,分析中的起始晶场参数是用晶场的三参数理论从晶场相互作用的简单点电荷计算得出的。概括了本文和前两篇论文的实验和理论的结果。
At 4K, 77K, the energies of most ortho-trivalent lanthanide series cluster photoacoustic and StarK splitting components in the C_ and C_2 lattice of yttrium oxide (Y_2O_3) were identified by far-infrared absorption spectroscopy. The electron Raman spectra , Through which can identify the components of low-energy excited clusters, systemically, using C_3 ~ i symmetry of the crystal field Hamiltonian operator analysis of the data structure of the energy level diagram, the analysis of the starting crystal field parameters using the crystal field The three-parameter theory is calculated from the simple point charge of the crystal field interaction. This article summarizes the experimental and theoretical results of this article and the first two papers.
