MgO对Sr2SiO4∶Eu2+荧光粉发光性质的影响
Effect of MgO Doped Concentration on Luminescence Properties in Sr2 SiO4 ∶ Eu2 + Phosphor
摘要
Abstract
MgO-doped Sr2SiO4: Eu2+ phosphors were synthesized. The introduction of MgO strongly enhances the blue and yellow emission intensity of Sr2SiO4 : Eu2+ phosphors. The luminescence properties as a function of MgO and Eu2+ concentrations were studied. White light emission phosphors were obtained when the molar ratio of Mg and Si is around 1. 0 under excitation of 400 nm. White light-emitting diode through the integration of InGaN near-UV chip and Sr2 SiO4: Eu2 + , MgO phosphor was fabricated and exhibited better characteristic parameters than that of the α'-Sr2SiO4: Eu2+ and β-Sr2SiO4: Eu2 + phosphors.关键词
