摘要：

Low-voltage cathodoluminescence and vacuum ultraviolet-excited photoluminescence were investigated for Tm3+-doped phosphor LiGd(PO3)(4):0.05Tm(3+) and un-doped phosphor LiGd(PO3)(4), showing that the photon cascade emission of Gd3+ can be fulfilled upon low-voltage electron beam and 195 nm light excitation, but this process can not be realized at 160 nm excitation. The different spectroscopic feature was discussed in terms of the excitation type and the energy transfer.
