Ce3+/Eu2+ co-doped LiBaBO3 phosphor was synthesized by high temperature solid-state reaction method,and its luminescent characteristics were investigated.The hues of the LiBaBO3:Ce3+,Eu2+ phosphor varies from blue to white and eventually to yellow-green by properly tuning the Ce3+/Eu2+ ratio.Under UV excitation,white light was generated by coupling blue and yellow-green emission bands attributed to Ce3+ and Eu2+ emissions,respectively.The luminous efficacy of LiBaBO3:1%Ce3+,2%Eu2+ calculated from the emission spectrum was about 290 lm/W.
