By using inorganic salts as raw materials and citric acid as chelating agent, (Gd,Y)AlO 3 :Eu 3+ phosphors were prepared by citric-gel method. The single phase of samples was obtained at 1000°C, which is 600°C lower than that of traditional solid state reaction. In the excitation spectrum of Gd 0.95 Eu 0.05 AlO 3 (λem=614nm), the broad bands with maximum at...
