AI Article Synopsis
- Researchers created aluminum-capped nanoslit arrays on a polycarbonate substrate using hot embossing and thermal evaporation, which served as a transparent window for blue-emitting polymer light-emitting diodes (PLEDs).
- The nanoslit arrays enhanced the external quantum efficiency of the PLEDs by utilizing surface plasmon polaritons, resulting in a maximum current efficiency of 4.84 cd/A.
- This efficiency was more than 2.2 times higher than that of a standard reference PLED, highlighting the potential of periodic nanostructures for creating high-performance and cost-effective polymer optoelectronic devices.
Article Abstract
Periodic aluminum-capped nanoslit arrays were produced on a polycarbonate plastic substrate by rapid hot embossing nanoimprint lithography and thermal evaporation, and they were used as a transparent window for blue-emitting polymer light-emitting diodes (PLEDs). The external quantum efficiency of blue-emitting PLEDs was enhanced by the surface plasmon polaritons of the periodic aluminum-capped nanoslit arrays. A maximum current efficiency of 4.84 cd/A was achieved for the proposed PLED, which was over 2.2 times that of the reference PLED (2.18 cd/A). These results demonstrate that periodic nanostructure can assist in the simple and low-cost fabrication of high-performance polymer optoelectronic devices.
