Abstract
The NIR phosphor Sr 3 SiAl 10 O 20 , which realizes ultra-broadband emission via dual energy transfer within two Cr 3+ emitters and Cr 3+ → Yb 3+ , can be used for NIR pc-LEDs, showing great potential in the fields of night-vision illumination, nondestructive surveillance, and information encryption.
