Synthesis of Ba₃Si₆O₁₂N₂:Eu²⁺ and Ba₃Si₆O₉N₄:Eu²⁺ phosphors using Si₂N₂O as the starting material

Abstract

Ba₃Si₆O₁₂N₂:Eu²⁺ and Ba₃Si₆O₉N₄:Eu²⁺ phosphors were synthesized by a solid-state reaction using Si₂N₂O powder as the starting material. The Ba₃Si₆O₁₂N₂:Eu²⁺ phosphor showed green photoluminescence (PL) with a peak at 517 nm, while Ba₃Si₆O₉N₄:Eu²⁺ showed bluish-green PL with a peak at 490 nm. Additionally, both phosphors exhibited afterglow properties.
