摘要
采用溶胶凝胶法和微波辐射法制备了Mn2+,Dy3+Mg2:SiO4红色发光材料。研究了以Mg2:SiO4为基质,在单一掺杂Mn2+的情况下,微波合成时间和Mn2+的掺杂浓度对材料发光性能的影响。选择最佳微波合成时间和Mn2+的掺杂浓度,研究了共掺Dy3+浓度对材料发光性能的影响。通过这种方法制备了在410 nm激发下,发光中心位于690 nm的红色发光材料。
Abstract
Sol-gel and microwave radiation methods are used to synthesize red phosphors of Mg2:SiO4 doped with Mn2+ and Dy3+. The effect of the concentration of Mn2+ and the microwave synthesis time on luminescence spectra is investigated. In the co-doped samples, the influence of concentration of Dy3+ on luminescence spectra is also investigated. The red color phosphors of Mn2+, Dy3+Mg2:SiO4, which can be excited effectively under 410 nm radiation, are obtained by means of these two methods. The samples show a red emission peaked at 690 nm.
