Light-emitting device |
abstract |
Disclosed is a light-emitting device ( 1 ) including a light-emitting element ( 2 ) emitting primary light, and a light converter ( 3 ) absorbing a part of the primary light emitted from the light-emitting element ( 2 ) and emitting secondary light having a longer wavelength than the primary light. The light converter ( 3 ) contains a green light-emitting phosphor ( 4 ) and a red light-emitting phosphor ( 5 ). The green light-emitting phosphor ( 4 ) is composed of at least one phosphor selected from a divalent europium-activated oxynitride phosphor substantially represented by the following formula: Eu a Si b Al c O d N e and a divalent europium-activated silicate phosphor substantially represented by the following formula: 2(Ba 1-f-g MI f Eu g )O.SiO 2 , while the red light-emitting phosphor ( 5 ) is composed of at least one phosphor selected from tetravalent manganese-activated fluoro-tetravalent metalate phosphors substantially represented by the following formulae: MII 2 (MIII 1-h Mn h )F 6 and/or MIV(MIII 1-h Mn h )F 6 . Consequently, the light-emitting device ( 1 ) has excellent color gamut (NTSC ratio). |
