A multifunctional solution-processed composite hole-injection layer (HIL), based on the blends of magnetic nanoparticles (NPs) Fe₃O₄@G–poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), Fe₃O₄@SiO₂–PEDOT:PSS and Fe₃O₄@Au–PEDOT:PSS, was used for application in high performance tris-(8-hydroxyquinoline) aluminum-based organic light emitting diodes (OLEDs). Compared to the control devices, a significant increase in the current efficiency of OLEDs with a composite HIL was realized, achieving maximum luminous efficiencies of 5.13 cd A⁻¹ (Fe₃O₄@G–PEDOT:PSS and Fe₃O₄@Au–PEDOT:PSS HIL), and of 4.83 cd A⁻¹ (Fe₃O₄@SiO₂–PEDOT:PSS HIL), corresponding to a 35% and 38.2% increase in current efficiency, respectively. The increase in the performance of the OLEDs is attributed to the collective effects of light-scattering, localized surface plasmon resonance (LSPR) and the magnetic effect induced by the magnetic NPs in the HIL.

磁性纳米颗粒/ PEDOT：PSS复合空穴注入层，用于高效有机发光二极管†

基于磁性纳米粒子（NP）Fe ₃ O ₄ @ G–聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）的混合物的多功能固溶处理复合空穴注入层（HIL ）， Fe ₃ O ₄ @SiO ₂ -PEDOT：PSS和Fe ₃ O ₄ @ Au-PEDOT：PSS被用于高性能的三-（8-羟基喹啉）铝基有机发光二极管（OLED）。与控制设备相比，采用复合HIL的OLED的电流效率得到了显着提高，实现了最大发光效率达5.13 cd A ^-1（Fe ₃ O ₄ @ G–PEDOT：PSS和Fe₃ O₄ @ Au–PEDOT：PSS HIL）和4.83 cd A^-1（Fe₃ O₄ @SiO₂ –PEDOT：PSS HIL），分别对应于电流效率提高35％和38.2％。OLED性能的提高归因于光散射，局部表面等离振子共振（LSPR）的集体效应以及HIL中磁性NP引起的磁性效应。
