Abstract

This study was carried out to characterize the crystal structure and luminescence properties of Eu²⁺ doped red-emitting Ba ₂Si₅N₈ phosphor. In this research, Ba ₂Si₅N₈ phosphors with various Eu compositions were prepared by normal pressure sintering (NPS). Ba₃N₂, Si₃N₄ and Eu₂O₃ were sintered at a high temperature in a mixture of N₂ and H₂. The crystal structure was analyzed by X-ray diffraction(XRD), and the photoluminescence(PL) properties of the Eu²⁺ - activated Ba₂Si₅N ₈ phosphors were evaluated as a function of the Eu²⁺ activator concentration. The red-emitting Ba₂Si₅N ₈ phosphors showed a broad excitation band range as well as high quantum output.
