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 2Eg 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 2Eg 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.
