英文摘要	Excitation and emission spectra of new borate La2CaB10O19 doped Eu3+ in VUV-VIS range, high resolution emission spectra at room temperature and lifetime of Eu3+ were investigated. The emission line at about 616 nm attributed to the D-5(0) - F-7(2) transition of Eu3+ is the most intense emission of Eu3+. The broad band at about 244 nm is originated from charge transition band (CTB) of O-2 --> Eu3+. According to the numbers of spectral lines D-5(0) - F-7(0) and D-5(0) - F-7(1) in high-resolution spectrum, Eu3+ ions occupy two crystallographic sites. The lifetimes of D-5(0) - F-7(0) transition of Eu3+ of two kinds of lattice sites are individually 2.1 and 2.6 ms, and both are exponential decay. In the VUV excitation spectrum, complicated band between 130 and 170 nm consists of host absorption and f-d transition of Eu3+.
