Definitions
- the present invention relates to a phosphor, a light emitting device, and a light emitting diode. More specifically, the present invention relates to a phosphor having low temperature dependency of light emission avoidance and excellent thermal stability, a light emitting device including the phosphor, and a light emitting diode.
- the phosphor is used in a light-emitting device (for example, a white diode, hereinafter referred to as a “LED”) that uses light in the ultraviolet to blue region as an excitation source.
- a white LED for example, the formula Y 3 A 1 5 ⁇ 12: compounds represented by C e (JP-10 242 513 JP); (B ai - Z S r x Ca y) 2 S i0 4: compound represented by the Eu z, A compound represented by the formula L i 2 S r S i0 4 : Eu (International Publication No. 03 No. 8063 Pamphlet) is known.
- the present invention provides a compound represented by the formula (1), and a phosphor I containing Io Eu (I as Eu).
