NOVEL NIR BROADBAND EMITTING PHOSPHORS FOR INFRARED SPECTROSCOPY

摘要

A luminescent material is disclosed with emission in the near infrared wavelength range, the luminescent material including Sc_1-x-yA_yRE:Cr_x, wherein MO = P₃O₉, BP₃O_12, SiP₃O₁₂; A = Lu, In, Yb, Tm, Y, Ga, Al, where 0 ≤ x ≤ 0.75, 0 ≤ y ≤ 0.9. A wavelength converting structure including the luminescent phosphor is also disclosed.
