市售的Ir络合物已被用于通过使用适当的热处理和适当调整层组成来制备高效（见图）单层磷光聚合物发光二极管。这些器件基本上没有表现出驱动场对Ir络合物浓度的依赖性，这表明层中空间电荷的积累是微不足道的。
A commercially available Ir complexhas been employed for the preparation of highly efficient (see Figure) single‐layer phosphorescent polymer light‐emitting diodes by use of appropriate thermal treatment and proper adjustment of the layer composition. These devices exhibit essentially no dependence of the driving field on the concentration of the Ir complex, suggesting that the build‐up of space‐charge in the layer is insignificant.
