摘要: Abstract Ce 3+ /Eu 2+ co-doped LiBaBO 3 phosphor was synthesized by high temperature solid-state reaction method, and its luminescent characteristics were investigated. The hues of the :Ce , Eu varies from blue to white eventually yellow-green properly tuning ratio. Under UV excitation, light generated coupling emission bands attributed emissions, respectively. luminous efficacy :1%Ce 2%Eu calculated spectrum about 290 lm/W.
