无机磷光体在实现节能、磷光体转换的发光二极管（LED）照明和显示技术方面至关重要。提高发光效率和改善这些灯的颜色质量的努力导致了磷光体主体结构和激活剂的不同组合的报告激增，许多人声称新材料具有变革性的特性。这篇透视文章概述了荧光粉必须满足的光学性能要求，以影响该领域。此外，已开发的工具，以加快发现特殊的荧光粉，满足这些要求进行了总结，包括晶体化学设计规则，代理，数据驱动的方法，第一原理计算和组合方法。我们还强调了磷光体发现领域面临的挑战。最后，我们讨论的现实，这些方法是不可能确定一个完美的磷光体，满足所有的要求。相反，我们提出了一个磷光体发现的工作流程，优先考虑生产下一代磷光体材料所需的特性。
Inorganic phosphors have been crucial in enabling energy-efficient, phosphor-converted light-emitting diode (LED) lighting and display technologies. The push to increase the luminous efficacy and improve the colour quality of these lights has led to a surge in reports of different combinations of phosphor host structures and activators, with many claiming that the new materials have transformative properties. This Perspective article outlines the optical property requirements phosphors must meet to impact the field. Additionally, the tools that have been developed to accelerate the discovery of exceptional phosphors that meet these requirements are summarized, including crystal–chemical design rules, proxies, data-driven approaches, first-principles calculations and combinatorial methods. We also highlight open challenges in the field of phosphor discovery. Finally, we discuss the reality that these methods are unlikely to identify a perfect phosphor that satisfies all the requirements. Instead, we propose a workflow for phosphor discovery that prioritizes the properties necessary to produce next-generation phosphor materials.
