Abstract
Several polymeric electroluminescent (EL) devices, possessing the poly (p-phenylenevinylene) (PPV) and polyimide LB films used as the light e mitting layer and the hole transporting layer respectively, were fabri cated by the LB technique. In these heterostructural EL devices, the l uminance over 100 cd/m(2) was achieved, which was more than 10 times h igher than that of the single layer (PPV LB film only) device. Further more, by incorporation of the hole transporting layer to the EL device s, remarkable improvements in charge injection and EL efficiency were observed. These improvements could be controlled by varying the thickn ess of the hole transporting layer.
