Luminescent Properties of Red Phosphors Prepared by Sol-Gel and Microwave Radiation Methods
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.
