简介 PROBLEM TO BE SOLVED : To provide a light-emitting device emitting slightly reddish warm-colored white light in high luminous efficiency and obtain a fluorescent material to be used in combination with a blue-light emitting element, or the like, and having an emission spectrum extending from yellow to red region. SOLUTION : The light-emitting device contains an Mn-doped Sr-Ca-Si-N : Eu, Z-type silicon nitride fluorescent material 11 (Z is a rare earth element such as Pr, La and Tb) having an emission spectrum extending from yellow to red regions by converting the wavelength of a part of an emission spectrum excited by a blue-light emitting element 10.
