Preparation and luminescent Properties of Zn2SiO4∶Mn2+

摘要：

　　Zn2SiO4∶Mn2+ was synthesized via a dipping method.Stoichiometric high pure SiO2 was put into the solution of zinc nitrate and manganese nitrate.The mixture was milled while being heated until the water was vaporized completely.The as-received mixture was added into the ethanol,and dispersed well,then the mixture was milled and heated to remove the ethanol thoroughly by evaporation.The precursor were dried for several hours at 60℃,and annealed in a reducing atmosphere of active carbon at 1000℃ for 4 h.As-prepared powders of Zn2SiO4∶Mn2+ was tested by XRD and SEM.Its luminescent properties were characterized by excitation and emission spectra.The results are compared with those of Zn2SiO4∶Mn2+ prepared by a general solid state reaction.
