摘要
Abstract
High brightness red phosphor Yax ( VP)O4 : Eu3+ and Y0.94Lny ( VP) O4 :Ey0.063+ (A = Mg, Ca,Sr,Ba;Ln = La,Ga) particles were prepared by coprecipitation process. The sample was investigated by X-ray diffraction (XRD) , scanning electron microscope (SEM) , excitation spectra and emission spectra. The particles were spherical shape. Aggregation between particles was not observed. The phosphor particles had very high emission intensity. The main excitation peak of the particles was 300 nm. The main peak for the emission spectra was 620 nm. Emission intensity of Yax (VP)O4: Eu3+ phosphor doped with little Sr and Ba could be improved. Emission intensity of Yax (VP) O4: Eu3+ phosphor showed a decreasing trend with Ca and Mg. Emission intensity of Y0.94-yLny (VP)O4: Eu0.063+ (Ln = La,Ga) could be improved evidently when doped with La3+ and Ga3+. The phosphor showed red emission with good color purity under 300 nm light excitation. This phosphor is a good substitution for (Y, Gd) BO3 : Eu3+ in PDP.关键词
