Progress of Ce3+/Eu2+ doped phosphors for violet chip based full-spectra lighting

Abstract

White light-emitting diodes (WLEDs) are used in various lighting scenes because of their merits such as low energy consumption, high brightness, long lifetime, portable size, etc. In a recent development, full-spectra WLEDs with uniform spectra and a high color rendering index (CRI) have attracted more attention. The discovery and design of phosphor materials suitable for full-spectra WLEDs is a more recent research hotspot. In this review, the evolution of artificial lighting and the requirements for full-spectra WLED fabrication are outlined. First, the research progress of Ce3+/Eu2+ doped phosphors that can be excited by violet light, including structural models and spectral regulation, is summarized. Second, high-performance multi-color phosphors with high quantum efficiency and luminescence thermal stability are screened for full-spectra WLEDs. Finally, the development prospects and challenges of Ce3+/Eu2+ doped phosphors for full-spectra lighting are demonstrated. This review will not only promote the research of Ce3+/Eu2+ doped phosphors for full-spectra WLEDs but also contribute to a thorough comprehension of full-spectra lighting. It also helps to develop more Ce3+/Eu2+ doped phosphors with better luminescence properties meeting the requirements for full-spectra WLED encapsulation.
