White Organic Light-emitting Devices Using Organic/Inorganic Color Conversion Film
A novel white organic light-emitting device (WOLED) using a strategy of exciting organic/inorganic color conversion film with a blue organic light-emitting diode (OLED) is reported.The luminescent layer of the blue OLED is prepared by using of CBP host blended with a blue highly fluorescent dye N-BDAVBi.The organic/inorganic color conversion film is prepared by dispersing a mixture of red pigment VQ-D25 and YAG phosphor in PMMA.A novel WOLED with the high color stability by optimizing the thickness and fluorescent pigment concentration of the color conversion film are achieved.When the driving voltage varied between 6 V to 14 V,the color coordinates varied slightly from (0.354,0.304) to (0.357,0.312) and the maximum current efficiency is about 5.8 cd/A(4.35 mA/cm2),the maximum brightness is 16 800 cd/m2 at the operating voltage of 14 V.
