Synthesis and the luminescent properties of silicate NaAISiO_4:Eu~(2+) phosphor using SiO powder as a silica source

摘要

A yellow-emitting NaAlSiO_4:Eu~(2+) phosphor was synthesized using SiO powder as a reducing agent and a silica source material. The emission intensity of the NaAlSiO_4:Eu~(2+) phosphor synthesized using SiO powder is higher than that of a sample produced using a conventional silicate phosphor synthesis reaction using SiO_2 powder. The ratio of non-reduced Eu~(3+) ions in the NaAlSiO_4:Eu~(2+) phosphor synthesized using SiO powder was decreased by the reduction effect of SiO powder.
