Various colors of light emitting diodes(LED) and four-band white light sources are obtained using a violet LED and various phosphor films. BaMg 2 Al 16 O 27 :Eu(blue),SrGa 2 S 4 :Eu(green),andEu(TTA) 3 (PTA) (red) phosphors are dispersed in poly-vinyl-alcohol aqueous solutions, and phosphor films are prepared by coating the suspensions to PET film. The narrow band emission of Eu(TTA) 3 (PTA) phosphor has excellent red luminescent property for four-band white light excited by the violet LED.

Keywords:four-band white LED;violet LED;phosphor;display
