摘要：

The crystal-field splitting levels in YPO4 Eu3+ micro-crystals are investigated by the Zeeman splitting in photoluminescence spectrum. X-ray diffraction pattern and microscopic images indicate small tetragonal nano-particles attaching on the surfaces of the mainly hexagonal micro-crystals. The peaks correspond to the transitions from D-5(0) excited state to F-7(1) and F-7(2) ground states are split in pulsed high magnetic fields, crystal-field splitting levels associated with different magnetic moments are clarified, which are completely different from that was supposed by the X-ray, microscopy, and zero-field photoluminescence results.
