The inventive white-light emitting diode is characterized in that it comprises a source emitting radiation whose wavelength band ranges from 370 to 420 nm, a first blue and red-light emitting phosphor of formula Ba3(1-x)Eu3xMg1-yMnySi2O8 (1), wherein 0 < x 0,3 and 0 < y 0,3 and a second green-light emitting phosphor. In another embodiment, said diode comprises the same source and a single phosphor whose chemical composition is Ba3(1-x)Eu3xMg1-yMnySi2O8, wherein 0 < x 0,3 et 0 < y 0,3 and which is embodied in the form of a mixture of at least Ba2SiO4, Ba2MgSi2O7 and Ba3MgSi2O8 phases. The inventive diode can be used for a lighting device. |
