Organic Compound-ZnO Nanoparticles Blend for Efficient Hybrid Light-Emitting Diode

Surface defects have a significant impact on the performance of light-emitting diodes (LEDs). To reduce surface defects, surface passivation using zinc oxide (ZnO) nanoparticles utilizing the wet chemical precipitation method is effective. An LED is produced using capped ZnO. The structural components of an ITO/PEDOT:PSS/F8BT/1.ZnO/TPBi/LiF/Al-based LED demonstrates that the interaction of zinc oxide (1.ZnO) and poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT) at the interface leads to luminescence under an electric field. The current-voltage curve clearly demonstrates rectifying properties in the device, with a threshold voltage of about 5 V. At normal temperature, the device emits electroluminescence (EL) at a wavelength of roughly 527 nm (green) when forward bias is applied.
