Abstract

(Ce_0.67Tb_0.33)Mn_xMg_1-xAl ₁₁O₁₉ phosphor powder was synthesized using a simple sol-gel process. The chemical state and location of the Mn ion in the phosphor were investigated using X-ray photoelectron spectroscopy (XPS) and electron spin resonance (ESR). Effect of Mn ion on the luminescent properties excited by VUV (vacuum ultraviolet) was studied. The Mn ion exists as Mn²⁺ in the phosphor and is located at a tetrahedrally surrounded site. The emission spectrum excited by VUV is composed of lines from Tb³⁺ and Mn²⁺. The emission intensity of Tb³⁺ decreases while that of Mn²⁺ increases when the content of Mn²⁺ increases and concentration quenching occurs when x>0.05. Doping Mn²⁺ in the phosphor increases the brightness of the phosphor.
