摘要： 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 RwQxSiyNz, 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.

摘要： Phosphor, a preparation method for the phosphor, and a light emitting device having the phosphor. The phosphor comprises an inorganic compound which at least comprises an element M, an element A, an element D, and an element R; the element M is one or two elements selected from the group consisting of Lu, La, Pr, Nd, Sm, Y, Tb, and Gd and must comprise Lu; the element A is Si and/or Ge; the element D is one or two elements selected from the group consisting of O, N, and F and must comprise N; the element R is Ce and/or Dy. Since the ionic radius of Lu3+ is smaller than that of La3+, when the inorganic compound comprises element Lu, the original ligand site would be contracted. In order to reduce lattice distortion due to the ligand site contraction, the adjacent ligand site expands, and the photochromic property is adjusted.

摘要： A lutetium nitride-based phosphor and a light emitting device comprising the same, wherein the lutetium nitride-based phosphor comprises an inorganic compound, and the composition of the inorganic compound comprises at least an M element, an A element, a D element and an R element; the M element is one or two elements selected from a group consisting of Lu, La, Pr, Nd, Sm, Y, Tb and Gd, and necessarily comprises Lu; the A element is Si and/or Ge; the D element is one or two elements selected from a group consisting of O, N and F, and necessarily comprises N; the R element is Ce and/or Dy, and the atomic molar ratio of the Lu element in the M element is greater than 50%. Because the ion radius of Lu3+ is smaller than the ion radius of La3+, the light color performance thereof can be flexibly adjusted according to needs.
