| titleOfInvention | Phosphor, Manufacturing Method Thereof, and Light-Emitting Element Using the Same |
| abstract | The present invention relates to a phosphor capable of being effectively excited by an ultraviolet or purple light or blue light LED, a method for producing the same, and a light emitting device manufactured using the same. The above phosphors contain rare earths, silicon, alkaline earth metals, halogens and oxygen, and aluminum or gallium, and the chemical formula is aLn 2 O 3 · MO · bM ′ 2 O 3 · fSiO 2 · cAX e : dR (where Ln Is at least one metal element selected from the group consisting of Sc, Y, La, Pr, Nd, Gd, Ho, Yb and Sm; M is at least one metal element selected from the group consisting of Ca, Sr and Ba; M 'Is at least one metal element selected from Al and Ga; A is at least one metal element selected from the group consisting of Li, Na, K, Mg, Ca, Sr and Ba; X is at least one selected from F and Cl At least one metal element selected from the group consisting of Ce, Eu, Tb, and Mn; 0.01 ≦ a ≦ 2, 0.35 ≦ b ≦ 4, 0.01 ≦ c ≦ 1, 0.01 ≦ d ≦ 0.3, 0.01 ≤ f ≤ 3, 0.6 ≤ e ≤ 2.4). The phosphor of the present invention has a wide range of excitation wavelengths, high efficiency, uniformity, no mixing, and stability. Its manufacturing method is simple, free from pollution and low in cost. The fluorescent substance of this invention can be mix | blended with an ultraviolet light, a purple light, or a blue light LED, and can produce a novel light emitting element.n n n n LED, phosphor, light emitting element, excitation wavelength range, purple light, blue light |
