Abstract:
Spectroscopic properties of LiKGdF5:Er(2%),Dy(0.4%) single crystal grown by the method of hydrothermal synthesis were studied.The energy positions of absorption band for 4f105d of Dy3+ ions were determined through the measurement of excitation spectrum in the VUV region.The results show that the former is higher in energy than the later one.Under excitation into the 4f105d band of Er3+ ions,quantum cutting was archived and model presented.
