RED PHOSPHORS CAPABLE OF EMBODYING ENOUGH COLOR RENDERING PROPERTIES AND HIGH LUMINOUS EFFICIENCY, A MANUFACTURING METHOD THEREOF, AND A LIGHT EMITTING DIODE INCLUDING THE SAME
PURPOSE: Red phosphors are provided to have high luminance, thermally and chemically excellent stability, and to manufacture a light emitting device having high reliability and high power.;CONSTITUTION: Red phosphors are in chemical formula: A_z(Sr, M)2(Si, Al)O_(4-x)N_y:R(0x3, y=2x/3, 0.001z0.1). In chemical formula, A is at least one kind of element selected from a group consisting of Li, K and Na, M is at least one element selected from a group consisting of Ba, Mg and Ca. R is at least one element selected from a group consisting of lanthanum atoms and transition atoms. The red phosphors have emission peaks of the wavelength of 600-700 nm by blue light or UV wavelength as excitation source.;COPYRIGHT KIPO 2012
