Abstract

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.

颜色可调荧光粉的研究进展

荧光粉转换的白光发光二极管(w- led)因其具有寿命更长、效率更高、结构紧凑、可靠性高、功耗低、环保等优点，在下一代固态照明领域受到越来越多的关注。用于照明和显示的w- led的质量受到荧光粉的影响。人们一直致力于创造一种具有高效率、色稳定性、最佳显色指数和低相关色温的突破性单相白光发光荧光粉。本文介绍了稀土活化荧光粉的研究现状，以及稀土活化荧光粉在w- led中的应用。为了实现适合w- led的可调色发射，主要研究了掺杂无机主体荧光粉的敏化剂和活化剂之间的能量传递机制。在本文中，我们还介绍了最近关于Eu2+， Mn2+， Tb3+， Sm3+， Ce3+和Tb3+之间能量传递机制的研究。也可以简要地强调电荷补偿和其他取代的影响，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。

期刊介绍： Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications. The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms. Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC). Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
