A novel dazzling far-red-emitting phosphor NaLaCaTeO:Mn (NLCTO:Mn) with superior photoluminescence properties was found via an ionic couple substitution strategy of Na + La for 2Ca in non-luminous CaTeO:Mn for the first time, which is originated from the significant distortion of TeO octahedra. The results indicate that the ionic couple substitution strategy is a feasible guide to explore novel Mn-involved oxide phosphors for potential application in plant cultivation LEDs.
通过在无光的CaTeO:Mn中用Na + La离子对替代2Ca的离子对替代策略,首次发现了一种具有优异光致发光性能的新型耀眼远红光发射荧光粉NaLaCaTeO:Mn (NLCTO:Mn),这源于TeO八面体的显著畸变。结果表明,离子对替代策略是探索新型含锰氧化物荧光粉以用于植物栽培LED潜在应用的可行指南。
