摘要The excitation and emission spectra of La2CaB10O19 : Ce3+ in VUV-Vis range were investigated. Three bands peaking at 307, 330 and 356 nm in emission spectrum and six bands peaking at 194, 224, 243, 260, 274 and 318 nm in excitation spectra are observed. This fact indicates that Ce3+ ions occupy two kinds of lattice sites in La2CaB10O19, one kind is substituted for La3+ with coordination number ten and the other is substituted for Ca2+ with coordination number eight. This result is consistent with that of La2CaB10O19 : Eu3+. When Eu3+ is used as a structural probe, two D-5(0)-->F-7(0) transitions peaking at 576.8 and 578.8 nm are observed in the emission spectrum. This indicates that Eu3+ ions also occupy two kinds of lattice sites in La2CaB10O19. The broad band peaking at 162 nm can be attributed to the host absorption, and the charge transition band(CTB) of O2--->Ce3+ may be obscured in this broad band.
