摘要：

We demonstrate an approach for realizing colour-controllable light emission from top-emitting organic light-emitting diodes (TEOLEDs) by utilizing exterior multilayer films overlaid on them. The emissive colour varies from blue to red for the TEOLED with green tris(8-quinolinolato) aluminium as the emissive layer by tuning the exterior multilayer films. The theoretical simulation of the electroluminescence for the colour tunable TEOLEDs is demonstrated and accords well with experimental results. The advantage of this approach is that the optical and electrical characteristics of the TEOLED can be controlled individually and hence provides the feasibility to realize a full-colour display by using white TEOLEDs.
