Broadband short-wave near-infrared-emitting phosphor MgNb2O6:Cr3+ for pc-LED applications

Novel MgNb 2 O 6 :Cr 3+ phosphors ( D q / B ∼ 1.65) yield broadband short-wave NIR emission peaking at 970 nm (FWHM = 155 nm, IQE ∼85.5%, EQE ∼25.2%). A self-built pc -LED works well for bioimaging, nondestructive detection, intelligent identification, etc .
