摘　　要：在介绍晶体中稀土离子4 fN-15d组态的能级结构、4 fN组态和4 fN-15d组态之间f-d跃迁线强以及相应的声子伴随跃迁的基础之上,讨论了国际上用于数值化模拟稀土离子f-d跃迁光谱的扩展f-shell程序的使用细节,总结了使用该程序在模拟f-d跃迁光谱方面的工作,并简单探讨了进一步的工作设想。最后,给出了一个氟冰晶石掺Er3+离子f-d跃迁光谱的数值模拟示例。The parameterized fitting calculations of f-d transition spectra of rare-earth ions doped in crystals were presented, which mainly consists of three sections： energy structure of 4f^N-1 5d configuration, f-d absorption line strengths between 4f^N and 4f^N-1 5d configurations and phonon-assisted f-d transition. The usage of the extended f-shell programs corresponding to the parameterized fitting calculations were discussed in detail. The works related to the program usage were reviewed and some suggestions on further works were proposed. As an example, the f-d excitation spectrum of the elpasolite crystal Er^3＋ ： Cs：NaYF6 was calculated and simulated.
