Abstract

Phase-pure crystalline La₂Hf₂O₇ doped with activators were directly synthesized through combustion process and glycine as a fuel. The basic luminescent properties of Eu³⁺, Tb³⁺, Pr³⁺, Ce³⁺ or Ti⁴⁺ in La₂Hf ₂O₇ were investigated. Luminescence was not observed in La₂Hf₂O₇:Ce, probably due to the luminescence of Ce³⁺ being completely quenched by the impurities in La ₂Hf₂O₇. All the other activators doped La ₂Hf₂O₇ samples show bright luminescence under UV excitation.
