中文摘要：
采用溶胶-凝胶法和微波辐射法制备了Mg2SiO4：Mn^2＋,Dy^3＋红色发光材料。研究了以Mg2SiO4为基质,在单掺杂Mn2＋的情况下,微波合成时间和Mn2＋的掺杂浓度对发光性能的影响。选择最佳微波合成时间和Mn2＋掺杂浓度,研究了共掺Dy3＋浓度对材料发光性能的影响。通过这两种方法制备了在410nm激发下,发光中心位于690nm的红色发光材料。
英文摘要：
Red phosphor of Mg2SiO4co-doped with Mn2＋and Dy3＋was synthesized by Sol-Gel and microwave radiation methods.The effect of concentration of Mn2＋and microwave synthesis time on luminescence spectra of Mg2SiO4：Mn2＋was studied.In the co-doped samples,the influence of concentration of Dy3＋on luminescence spectra was investigated.The red phosphor of Mg2SiO4：Mn2＋,Dy3＋,which could be excited effectively under 410nm radiation and showed an emission peak at 690nm,were obtained by these two methods.
