LED LED red fluorescent material and lighting device having same

摘要

The present invention provides an LED red fluorescent substance and a light emitting element containing the fluorescent substance. The fluorescent material is composed of at least one element selected from the group consisting of B, Al, Ga, In, La, Gd, Lu, Sc and Y and at least one element selected from the group consisting of Ba, Mg, Ca, Sr, An element A containing at least one element and a element D containing at least one element of at least one of Si, Ge, C, Sn, Ti, Zr and Hf and at least one element of N, And at least one element selected from the group consisting of S, Se and Te or an L element containing at least one element and at least one element selected from the group consisting of rare earth elements or transition metal elements. The fluorescent material of the present invention has advantages such as high luminous efficiency, good temperature characteristics and wide half-width, and can be used alone or in combination with other fluorescent materials to manufacture high-performance light emitting devices.
