A Study on the Luminescent Properties and Energy Transfer of Na₂BaMgP₂O₈:Tb³⁺, Eu³⁺ Phosphor

Abstract:

Na₂BaMgP₂O₈ phosphors were synthesized by a standard solid state reaction and their luminescent properties were investigated. The phase structure was analyzed by X-ray powder diffraction measurement. Under the excitation of 365nm, Na₂BaMgP₂O₈:Tb³⁺, Eu³⁺ phosphors show two color bands of green and red color due to ⁵D₄−⁷F₅ transition of Tb³⁺ ions and ⁵D₀−⁷F₂ transition of Eu³⁺ ions, respectively. The emission intensity of Tb³⁺ deceased with the increasing concentration of Eu³⁺, which verified that an effective energy transfer occurred from Tb³⁺ to Eu³⁺ in Na₂BaMgP₂O₈ host. The present study indicated that the phosphors have a high potential application in solid state lighting.
