摘　　要：将发光层进行多次堆叠,构造出有机电致发光器件。在堆叠过程中,改变各发光层厚度的相对比例,发现在总厚度相同、结构相同,而各发光层比例不同的条件下,器件呈现不同的发光特性。器件的电致发光光谱有着明显的变化,器件颜色由蓝光到近白光改变极其明显,器件的亮度和器件的效率也有不同程度的改变。Designed is a multilayer orgnic light-emitting device with statcks structure of DPVBi and Alq as emitting layer. In the process of stacking, changing the relative proportions of emission layer, it is found that the devices had different performances under same total thickness and same strcture but diverse emission layers. There is a clear electroluminescent spectral changes, the color of the device changes from blue to white obviously,and its brightness and the efficiency had different degrees of change.
