中文摘要：

用CzHQZn作为受主,利用磷光敏化的方法制备了有机电致黄光和白光器件。黄光器件采用Ir（ppy）3掺杂4,4-N,N′-=咔唑基联苯（CBP）,敏化新的黄光材料CzHQZn作为发光层,当发光层厚度为18nm时器件性能最好,最大发光效率为3.26cd/A（at10V）,最大发光亮度为17560cd/m^2（at10V）;白光器件采用多发光层结构,结合ADN的蓝光复合发光,同时加入了电子阻挡层（NPBX）和空穴阻挡层（BCP）,获得的白光器件最大发光效率为2.94cd/A（at8V）,最大亮度为11089cd/m^2（at13V）。

英文摘要：

The yellow and white organic light-emitting devices（OLEDs） are fabricated by using phosphorescence sensitizing（E）-2-（2-（9-ethyl-9H-carbazol-3-yl）vinyl）quinolato-zinc（CzHQZn）.The yellow OLED can be fabricated using CzHQZn sensitized by a phosphorescent material,fac tris（2-phenylpyridine）iridium[Ir（ppy）3],as a yellow light-emitting layer.When the emitting layer thickness is 18 nm,a series of yellow devices are fabricated,which have the maximum luminous efficiency of 3.26 cd/A-1 （at 10 V）and the maximum luminance of 17 560 cd/m-2 （at 10 V）.The white OLED can be fabricated with a multilayer structure,through mixing two complememtary colors（blue/yellow） and NPBX as exciton blocker layer and BCP as a hole-blocking layer,respectively.The white OLED has the maximum luminous efficiency of 2.94 cd/A-1（at 8 V） and maximum luminance of 11 089 cd/m-2 （at 13 V）.
