摘要：

A new borate phosphor, La2CaB8O16:RE3+ (RE = Eu, Tb) has been synthesized by solid-state reaction method. The local lattice environment of doping ions in La2CaB8O16 has been determined by use of the room temperature and low temperature fluorescence spectra of Eu3+. The luminescent properties of RE3+-doped La2CaB8O16 have been investigated. The dominant emission of Eu3+ in La2CaB8O16 is located at 616 nm corresponding to the electric dipole transition D-5(0)-F-7(2), while the green emission of La2CaB8O16:Tb3+ attributed to the transition D-5(4)-F-7(5) is centered at 544 nm. The concentration dependence of the emission intensity shows that the optimum doping concentrations of Eu3+ and Tb3+ are 30 mol% and 15 mol%, respectively. (C) 2012 Elsevier B.V.
