摘要:

采用高温固相法合成红色荧光粉Sr2MgSi2O7:Eu3+,用扫描电镜、X射线衍射和荧光光谱表征样品的表面形貌、晶体结构、激发光谱和发射光谱。结果表明:制得的Sr2MgSi2O7:Eu3+为镁黄长石结构,属四方晶系。Sr2MgSi2O7:Eu3+的激发峰为250~600 nm的多峰分布,发射光谱包含了Eu3+在576、590、612、650 nm和700 nm处的5个特征发射峰;样品的发光强度随Eu3+掺量增加而增大;激活剂Eu3+的掺量、助熔剂的用量及烧结时间对样品的发光性能均有影响。

Red phosphor Sr2MgSi2O7:Eu3+ was synthesized by high temperature solid state reaction. Surface configurations, crystal structure and luminescence properties of the as-synthesized samples were characterized by scanning electronic microscopy, X-ray diffraction, and phosphorescent spectra. Results show that Sr2MgSi2O7 produced possesses an akermanite structure, belonging to a tetragonal system. Excitation peaks of Sr2MgSi2O7:Eu3+ in 250–600 nm have a multiple peak distribution. Emission spectra included five typical peaks at 576, 590, 612, 650 nm, and 700 nm of Eu3+. Luminescence intensity is strengthened with the increase of Eu3+ dosage. Activator Eu3+ dosage, assistant flux, and sintering time have an impact on the luminescence properties.
