演示了逐步设计无机单掺杂白色荧光粉的策略。该方法包括通过连续控制固溶体或纳米偏析主体基质的化学成分以及单一掺杂剂的氧化态来调节发射的不同贡献。我们使用这种方法设计了一种白色荧光粉 Na4CaMgSc4Si10O30:Eu，具有出色的显色性 (CRI > 90)，类似于常见的混合荧光粉光源，但为单相。我们表明，这种方法也可以扩展到其他荧光粉，用于生物医学或电信等多种应用。
A strategy to design step by step an inorganic single-doped white phosphor is demonstrated. The method consists in tuning different contributions of the emission by successively controlling the chemical compositions of the solid solution or nanosegregated host matrix and the oxidation states of the single dopant. We use this approach to design a white phosphor Na4CaMgSc4Si10O30:Eu with excellent color rendering (CRI > 90) that is similar to common mixed-phosphor light sources but for a single-phase. We show that this methodology can also be extended to other phosphors for use in diverse applications such as biomedicine or telecommunications.
