Abstract

Inorganic luminescent materials are highly demanded for solid-state white lighting. Rare-earth Ce³⁺ ions activated garnet phosphors, as one of the most promising luminescent materials, have received tremendous attention for their potential applications in phosphor-converted white light-emitting diodes (pc-WLEDs), due to their high absorption efficiency, remarkable multi-color emissions, broadband emission spectra, high luminescence efficiencies, and excellent thermal stability. In this paper, recent advances in the developments of Ce³⁺-activated garnet phosphors for pc-WLEDs are reviewed. Firstly, the working principle of pc-WLEDs, the structural composition of garnet, the photoluminescence theory of Ce³⁺ ions, as well as the dominated factors affecting thermal stability and related thermal quenching mechanisms are highlighted. Secondly, several different synthesis methods of Ce³⁺-activated garnet phosphors are thoroughly elaborated, and the effects of these methods on the micro/nanoscale morphologies and luminescence properties are discussed. Thirdly, photoluminescence characteristics and thermal stability, as well as color stability of various color-emitting Ce³⁺-activated garnet phosphors together with their functional applications in pc-WLEDs are systematically summarized. Last, the remaining challenges and future development prospects of Ce³⁺-activated garnet phosphors in solid-state lighting are provided.

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.
