Discrimination of amazonian forest species by NIR spectroscopy: wood surface effects

Screening of Broadband Near-Infrared Cr3+-Activated Phosphors Using Ce3+ as a Probe

“…In recent years, the NIR spectroscopy technology has received great attention due to its broad applications in food detection, environmental monitoring, solar cells, and medical treatment. − NIR pc-LEDs, combining blue LED chips with NIR-emitting phosphors, are excellent candidates for such applications and superior to their counterparts, such as tungsten halogen lamps, as they have super-broad emission spectra, longer service life, lower cost, and smaller size. , As a key component in NIR pc-LEDs, NIR phosphors play an important role in regulating the spectrum, efficiency, and sensitivity of devices. , Recently, searching for highly efficient and broadband NIR phosphors has become a hot topic, and a variety of NIR phosphors have been reported. − …”
