A red phosphor has a peak of emission spectra of 600 and 650 nm, a peak width of up to 10 nm, and a fluorescence lifetime of at least five milliseconds at room temperature and is made of a Mn-activated complex fluoride phosphor represented by the following formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ K 2 SiF 6 :Mn€ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein an amount of Mn is up to 10 mol% relative to the sum of Mn and Si. |
