摘要：

A systematic spectroscopic study of the 4f(7) energy levels of Gd3+ in LiYF4, in the vacuum-ultraviolet spectral region (50000 - 70000 cm(-1)) is reported. Using energy-level calculations, all observed spectral lines could be assigned to free-ion term symbols (including term symbols with unusually high L and J, e.g., a (2)Q(23/2) level around 67000 cm(-1)). From the (6)G(J) levels around 50000 cm(-1) quantum cutting (or two-photon luminescence, photon-cascade emission) is observed: the emission of a red photon due to the (6)G(J)-->P-6(J) transition is followed by the emission of an ultraviolet photon due to the P-6(J)-->S-8(7/2) transition.
