以蓝色发光材料Liq为主体,以一定的比例掺入黄光染料Rubrene,研制了新型白色有机电致发光器件.调节Rubrene的掺杂比为1.1%时得到近白光器件,色坐标为(0.308,0.347),器件的启亮电压为8V,当外加电压达到25V时,器件发光亮度达3120cd/m^2.
A novel white organic light emitting device with a single layer consisting of an orange-red dopant 5,6,11,12-tetra- phenylnaphthacene (Rubrene) and a blue light emitting material 8-hydroxyquinoline lithium (Liq) mixed in a certain proportion was fabricated. When the proportion is 1.1%, the commission international De L' Eclairage (CIE) coordinate of the device is (0. 308,0. 347). The driving voltage of the device is 8V, and the luminescence brightness is 3120cd/m^2 when the voltage is increased to 25V.
