title: The Influence Mechanism of Halogen Ion on the Temperature Quenching Performance of Sr2SiO4:Eu Phosphors.
abstract: The luminescent properties of Sr2SiO4:Eu phosphors synthesized with and without flux have been investigated. With the co-dopation of NH4CI, the luminescent intensity of Sr2SiO4:Eu is increased and the temperature quenching property is improved. The effect of NH4Cl is analyzed not only from the crystallinity of the Sr2SiO4 crystal but also the band structure of Sr2SiO4 host, which is calculated by density functional method with the local density approximation.
