摘要	The effects of the 4f(2)5d configuration on the intraconfigurational 4f(3) <-> 4f(3) electric dipole transitions of Nd3+ doped YPO4 are taken into account by a 'direct' calculation. A simple model is applied to analyze the opposite-parity 4f(2)5d configuration admixing into 4f(3) transitional states. The matrix elements of the odd-rank crystal-field interaction and the interconfigurational electric dipole transition are directly expressed using a standard tensor operator method. A set of selection rules for f-d mixing and f-f electric dipole transitions is built up. The admixture effect is considered including both explicit 4f(2)5d configuration and other opposite-parity states such as the 4f(2)n'g configuration which is treated by a closure procedure. Using this calculation method in combination with the experimental data from the absorption spectrum, a set of intensity parameters is obtained. The transition intensities originating from the high-lying (2)G(9/2)(2) level to the lower energy levels are then calculated, demonstrating a good agreement with the experimental results. The new calculation method is suitable for the electric dipole transitions within the 4f(N) configurations of trivalent lanthanide ions with more than two f-electrons.
