Abstract

Eu²⁺-activated Ba₃Si₆O₁₂N ₂ green-emitting phosphors were synthesized by a solid-state reaction method. X-ray diffraction patterns showed that the synthesized phosphor sintered at 1200 °C for 12 h was a Ba₃Si₆O ₁₂N₂ pure phase. The synthesized phosphors were excited in UV to blue light. The emission spectra showed a broad green emission band when excited witha light at 465 nm. The highest emission intensity was observed ata Eu²⁺ concentration of 0.25 mol and the NH₄Cl concentration of the optimized flux was found to be 9wt.%. The obtained green-emitting Ba₃Si₆O₁₂N₂:Eu²⁺ phosphors could be applied to white LED applications.
