| 中文摘要 | A theoretical method for studying the inter-relation between electronic and molecular structure has been proposed by diagonalizing the complete energy matrices for d(5) configuration ion in a trigonal ligand-field. Based on this method, the local lattice distortion of Fe(3+) in AlF(3):Fe(3+) system (AlF(3) is the component of fluoride glasses or is the single crystal) has been studied by considering the second-order and fourth-order EPR parameters D and (a - F), simultaneously. The results indicate that the local lattice structure around octahedral Fe(3+) center has an expansion distortion whether AlF(3):Fe(3+) is the component of fluoride glasses or Fe(3+) is doped in the AlF(3) single crystal. The expansion distortion may be ascribed to the fact that the radius of Fe(3+) ion is larger than that of Al(3+) ion, and the Fe(3+) ion will push the fluoride ligand outwards, respectively. Furthermore, the thermal expansion coefficient of Fe(3+) in the single crystal AlF(3):Fe(3+) depending on the temperature are reported and some characteristics of it are also analyzed.
