Phosphor converted white light emitting diodes (w-LEDs) are garnering increasing attention in solid state lighting for the next generation of illumination due to their merits, including longer life, greater efficiency, compactness, reliability, low power consumption, and environmental friendliness. The quality of w-LEDs used in lighting and displays is affected by phosphors. There has been much focus on the creation of a ground-breaking single phase white light emitting phosphor with high efficiency, chromatic stability, an optimum color rendering index, and low associated color temperature. This review includes an introduction to rare earth activated phosphors as well as the basic benefits of phosphors for w-LEDs. To achieve the desired color-tunable emission suited for w-LEDs, the energy transfer mechanism between sensitizer and activator doped with inorganic host phosphors it primarily considered. In this article, we also covere a recent study on the energy transfer mechanism between Eu2+, Mn2+, Tb3+, Sm3+, Ce3+, and Tb3+. It is also possible to briefly emphasize the impact of charge compensation and other substitutions, such as (i) cationic, (ii) anionic, and (iii) cationic-anionic substitutions, on the color-tunable emission.

颜色可调荧光粉的最新发展:综述

荧光粉转换白光发光二极管 (w-LED) 由于其寿命更长、效率更高、紧凑、可靠性、低功耗和环境友好等优点,在下一代照明的固态照明中越来越受到关注。用于照明和显示器的 w-LED 的质量受磷光体的影响。人们一直非常关注创造具有高效率、色彩稳定性、最佳显色指数和低相关色温的突破性单相白光荧光粉。本综述包括对稀土激活荧光粉的介绍以及荧光粉对 w-LED 的基本优势。为了实现适合 w-LED 的所需颜色可调发射,它主要考虑了掺杂无机主体荧光粉的敏化剂和激活剂之间的能量转移机制。在这篇文章中,我们还介绍了最近对 Eu 之间的能量转移机制的研究。2+、Mn 2+、Tb 3+、Sm 3+、Ce 3+和Tb 3+。还可以简单地强调电荷补偿和其他取代,例如 (i) 阳离子、(ii) 阴离子和 (iii) 阳离子-阴离子取代对颜色可调发射的影响。
