Eu²⁺, Dy³⁺-doped SrAl2O4 was prepared by a hydrothermal reaction through the process of calcination at lower temperature. The physicochemical properties of the SrAl₂O₄: Eu²⁺, Dy³⁺ phosphor were characterized and compared to those of the SrAl₂O₄: Eu²⁺, Dy³⁺ prepared by sol-gel method. The photocatalytic properties of the SrAl₂O₄: Eu²⁺, Dy³⁺ were evaluated in photocatalytic water decomposition for hydrogen production. The SrAl₂O₄: Eu²⁺, Dy³⁺ prepared by hydrothermal reaction exhibited excellent phosphor properties which were similar with that prepared by sol-gel method. Its photocatalytic activity for hydrogen evolution was higher than that of TiO₂ photocatalyst.
