| titleOfInvention | A near-infrared phosphor and a light-emitting device containing the phosphor |
| abstract | The invention belongs to the technical field of luminescent materials, in particular to a near-infrared fluorescent powder, and also to a light-emitting device containing the fluorescent powder. The near-infrared phosphor contains an inorganic compound with a chemical formula of A x R p Q q O r :D y , wherein A is one or both of Zn, Ca, Mg, Sr and Ba elements, and R is Ga, Al and One or both of B elements, Q is one or both of Ge and Si elements, D is one or both of Ni and Yb elements, which must contain Ni element, 2≤x≤4, 1.5≤p≤2.5, 0.8≤q≤1.2, 6≤r≤10, 0.0001≤y≤0.2. This compound has the same crystal structure as spinel ZnGa 2 O 4 . The luminescent material of the present invention can emit efficiently in the near-infrared region (1250-1300 nm), is an ideal near-infrared luminescent material, and the light-emitting device containing the phosphor can be widely used in night vision monitoring, biological analysis sensing systems and Bio-imaging systems, etc. |
