Title: PHOSPHOR, METHOD FOR PRODUICNG PHOSPHOR, PHOSPHOR-CONTAINING COMPOSITION, LIGHT-EMITTING DEVICE, ILLUMINATING DEVICE, AND IMAGE DISPLAY DEVICE
Abstract:
Disclosed is a yellow-orange phosphor which has high brightness and excellent temperature characteristics and also has high brightness when mixed with a phosphor of a different color. Specifically disclosed is a phosphor containing a crystal phase represented by formula [I], wherein when the color of an object is expressed in the L*a*b* color system, the values of a*, b*, and (a*2+b*2)1/2 satisfy the relationships: -20≤a*≤-2, 71≤ b*, and 71≤(a*2+b*2)1/2, respectively.
