Electroluminescent devices based on cross-linked polymer blends

The effectiveness of electroluminescent devices, which were based on the cross-linked polymer blends, was discussed. Highest efficiency was shown by the cross-linkable blends at low concentrations of the hole transporting material. Significant improvements were observed in the performance of the single layer polymer organic light emitting diodes (OLED) because of the blending and morphological changes combined with blending.
