Synthesis, Crystal Structure, and Luminescence Properties of Y<sub>4</sub>Si<sub>2</sub>O<sub>7</sub>N<sub>2</sub>
Eu<sup>2+</sup> Oxynitride Phosphors
Y4Si2O7N2: Eu2+ phosphor has been prepared by a pretreatment method. Reduction in Eu3+ ions into Eu2+ by the use of hydrogen iodide (HI) is verified by X-ray absorption near-edge structure (XANES) and electrode potential analysis. Y4Si2O7N2: Eu2+ phosphor has a broad emission ban
