A RED EMITTING PHOSPHOR FOR LOW-VOLTAGE APPLICATIONS AND A METHOD OF PREPARING THE SAME

摘要

The present invention relates to a ZnGa ₂ O ₄ red phosphor added with Eu and a method of manufacturing the same. The red phosphor is prepared by adding a mixture Eu compound of ZnO and Ga ₂ O ₃ and then calcining at 1000 to 1200 ° C. for 1 to 3 hours. ZnGa ₂ O _{4, which} is a matrix of the phosphor of the present invention, contains an appropriate amount of Eu, so that the light emission start voltage is low, which is applicable to a low voltage display device such as VFD or FED.
