基于群链方法提出稀土离子在玻璃基质中的表观晶格 场哈密顿的简单模型.利用该模型较为系统地分析了在13K温度下采用常规方法测量的Er 3+离子在锗酸盐玻璃中的吸收和发射谱,确定了从Er3+离子4I15/2到 2H9/2所有多重态的Stark分裂值.%Based on the group chain scheme, a simple model of appar ent field Hamiltonian for rare eath ions in glasses was proposed. By means of th is model, the absorption and emission spectra of Er3+ ions in germanate gl ass measured at 13K in a conventional way were analyzed systematically and the S tark splittings of the manifolds from 4I15/2 to 2H9/2 we re determined.
