Although there have been numerous reports on broadband near-infrared (NIR) emitting phosphors, their emissions are mainly concentrated in the range of 700–1000 nm (NIR-I). Herein, we successfully synthesized a phosphor CaMgGeO4:Cr4+(CMG:Cr4+) with an emission 1000–1600 (NIR-II). The introduction Er3+ ions into CMG:Cr4+ resulted wider CaMgGeO4:Cr4+,Er3+ (fwhm = 361 nm), compensating for luminescence 1500–1600 nm. More importantly, energy transfer from Cr4+ to has discovered. Furthermore, NIR pc-LED was fabricated by combining CMG:Cr4+,Er3+ 590 chip. changes intensity and profile transmission spectra light passing through different liquids reveal its potential application organic compound recognition. This work opens direction development NIR-II phosphors.

In this work, a series of BaSrGd4O8:xBi3+ blue phosphors was synthesized employing the high-temperature solid-state method. Phase purity samples verified by X-ray diffraction and Rietveld refinement. Time-resolved photoluminescence spectra revealed existence two distinct Bi sites. Subsequent optimization dopant types doping levels in batch led to an almost twofold increase quantum efficiency. The introduction Eu3+ into facilitated construction energy transfer pathway. As concentration increased, emission color changed from purple finally red. addition, thermal stability potential applications were extensively investigated. Finally, WLED devices successfully fabricated with rendering indices 96.27 92.18, correlated temperatures 5198 2475 K. This underscores prospective application these field high-quality warm WLEDs.

Discovering multifunctional luminescent materials to meet the demands of modern spectroscopy is great significance. However, it a standing challenge enable multiple luminescence properties in single material system via metal ion doping. Here, we report inherently Bi3+/Bi2+ codoped Ca3Ga2Ge3O12 persistent phosphor where Bi3+ situ reduced Bi2+. This can act as an efficient multimodal material, which simultaneously exhibits long-lasting (>12 h) ultraviolet-B (UVB) and near-infrared (NIR) dual-band after irradiation by 254 nm ultraviolet (UV) light. UVB NIR afterglow are ascribed distinct Bi2+ emitters, respectively, proven comprehensive spectroscopic investigations including X-ray absorption near-edge structure spectra photoelectron spectroscopy. Besides, this also exceptional photochromic features, accompanied rapid body color transformation from white brown response UV light within 60 s excellent recovery capacity upon thermal or blue/white stimulation. The combination coupled with reversible white-to-brown photochromism phenomenon offers one type promising showing potential be used for optical storage anti-counterfeiting applications.
