Abstract

(Graph Presented) Ce³⁺ and Tb³⁺ co-doped Ba ₂Ln(BO₃)₂Cl (Ln = Y and Gd) green emitting phosphors were prepared by solid state reaction in reductive atmosphere. The emission and excitation spectra as well as luminescence decays were investigated, showing the occurrence of efficient energy transfer from Ce ³⁺ to Tb³⁺ in this system. The phosphors exhibit both a blue emission from Ce³⁺ and a green emission from Tb³⁺ under near ultraviolet light excitation with 325-375 nm wavelength. Emission colors of phosphors could be tuned from deep blue through cyan to green by adjusting the Tb³⁺ concentrations. The energy transfer efficiency and emission intensity of Ba₂Y(BO₃)₂Cl:Ce ³⁺,Tb³⁺ precede those of Ba₂Gd(BO ₃)₂Cl:Ce³⁺,Tb³⁺, and the sample Ba₂Y(BO₃)₂Cl:0.03Ce³⁺, 0.10Tb ³⁺ is the best candidate for n-UV LEDs.
