研究目的
Investigating the fabrication of polymer light-emitting diodes (PLEDs) using electrosprayed microparticle films as the active layer and exploring the color-tunable properties by combining different polymer materials.
研究成果
The study successfully demonstrates that optimized electrospraying can facilitate PLED fabrication with controllable emission properties by combining different polymers. This approach presents a new paradigm for easy fabrication of hybrid multimaterial-conjugated polymer-based optoelectronic devices.
研究不足
The uniformity of mixed polymer droplets based layers is relatively difficult to control, and the overall performance of these PLED devices is still modest.
1：Experimental Design and Method Selection:
The study involves optimizing electrospraying parameters to achieve uniform microparticle films for PLED fabrication.
2：Sample Selection and Data Sources:
ITO substrates are used as the base, with PEDOT/PSS and TFB layers spin-coated atop. MEH-PPV and F8BT polymers are electrosprayed to form the active layer.
