Abstract

The authors report here the enhanced luminescence properties of Sr Si2 O2 N2 doped with Eu and M (M=Ce, Dy, and Mn). The Eu and Eu, Mn-codoped powders were prepared by a solid state reaction at temperatures between 1400 and 1600 °C under H2 (25%) - N2 (75%) atmosphere. The Eu, M -codoped Sr1-x-y Si2 N2 O2 phosphors have the monoclinic structure with lattice parameters a∼15.6 Å, b∼16.2 Å, c∼9.4 Å, and Β∼91°. The phosphors can be efficiently excited in the UV to visible region, making them attractive as conversion phosphors for a light emitting diode application. A green-yellow emission was observed for Eu,M -codoped Sr1-x-y Si2 N2 O2. The addition of M in the Eu site in Sr Si2 O2 N2 remarkably enhances the luminescent intensity by the factor of 144%, 148%, and 168% for Ce, Dy, and Mn, respectively.
