Abstract

Spectroscopic properties of LiKGdF

: Er（2%）

Sm（0.4%） single crystal under UV laser and synchrotron VUV light excitation were studied. The energy positions of absorption band for the 4f

5d of Sm

and 4f

5d of Er

ions were determined through the measurements of excitation spectra in the VUV region. The results show that when the 4f

5d band of Er

ions was excited

quantum cutting was achieved. A model for the phenomena was also presented.
