Abstract

The optical properties of a Ce³⁺-ion-doped LiCaAlF₆ (Ce:LiCAF) crystal is investigated in the vacuum ultraviolet (YUV) region. It is found that the optical excitation from the valence band of the LiCAF crystal to the ²E_g excited state of Ce³⁺ can be utilized as an efficient excitation channel to obtain an ultraviolet emission due to the 4f-5d transition of Ce³⁺. Furthermore, the energy level of the ²E_g state is found to be located near the conduction band of the LiCAF crystal, which leads to the electron transfer from the LiCAF crystal to the active Ce³⁺ ion.
