A GREEN EMITTING PHOSPHOR FOR VUVVACUUM ULTRAVIOLET EXCITED LIGHT EMITTING DEVICE, A PREPARATION METHOD THEREOF AND A LIGHT EMITTING DEVICE COMPRISING THE SAME

摘要

The present invention comprises a green phosphor for a light emitting element for a vacuum ultraviolet excitation source , a method of manufacturing the same , and this relates to a light emitting element , the green phosphor is represented by the following formula (1) . ; [ Formula 1] ; Mg _x Al _4-2x O _6-2x : Mn _y ; (0.6 x 1.4, 0.01 y 0.1) ; The green phosphor of the present invention is excellent in brightness , color purity , the discharge characteristics , characterized in that the afterglow time is short The . In particular , heat in form of a stable spinel structure , the ion impact , and is very reliable, with respect to the effects of external , such as a vacuum ultraviolet light irradiation , there is an advantage in that the life of the light emitting element can be maintained for a long time .
