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.

Compared with conventional phosphor‐converted near‐infrared light‐emitting diodes (NIR pc‐LEDs), persistent LEDs ppc‐LEDs) are applicable not only in systems but also novel devices the fields of intelligent security, driverless vehicle technology, and virtual reality. However, NIR ppc‐LEDs have been extensively investigated. Herein, a prepared SrAl 12 O 19 : Fe 3+ , Mg 2+ Ti 4+ phosphors is designed. In relation to pc‐LEDs, new ppc‐LED exhibits full‐spectral responsive sensing ability during photostimulated mediation lattice defects. Furthermore, using as smart LED digital imaging system, optical feedback could be converted signal self‐regulated visible‐to‐NIR operation mode. These results imply that designed ppc‐LED, ability, greatly enhances sensitivity imaging, particularly low‐light which has recently drawn considerable attention advanced driver assistance VR/AR technology.
