Abstract
The present disclosure relates to the technical field of luminescent materials, and more particularly, to a nitride luminescent material and a light emitting device comprising the luminescent material. The nitride luminescent material recited in the present disclosure includes an inorganic compound with the structural composition RQSiN, the excitation wavelength of the luminescent material is between 300-650 nm, and the emission main peak of the NIR light region is broadband emission between 900-1100 nm; the excitation wavelength of the luminescent material is relatively broad and capable of excellent absorption of ultraviolet visible light, and has more intensive NIR emission as compared with NIR organic luminescent materials and inorganic luminescent materials of other systems, so it is an ideal application material for NIR devices.
