There is a growing demand for functional materials that can adjust light-emissive properties in organic optoelectronic devices. In this study, highly emissive and aggregation-induced emission (AIE) electroluminescent composite systems composed of a blend of nematic liquid crystals (NLC) and polyethylene-functionalized gold nanospheres (GNSs) are presented. The findings show superior electro-optical properties, such as a reduction in threshold voltage by approximately 24%. Additionally, the fall time and rotational viscosity are significantly reduced for different concentrations of GNS-blended liquid crystal cells. The increased UV absorbance and enhanced luminescence properties are attributed to surface plasmon resonance and AIE effect, making them suitable for new-age display applications.
A demand for functional materials that are capable of tailoring light-emissive properties has apparently been rising nowadays substantially for their utilization in organic optoelec-tronic devices. Motivated by such promising characteristics, we present highly emissive as well as aggregation-induced emission (AIE) electroluminescent composite systems composed of a nematic liquid crystals (NLC) blended with polyethylene-functionalized gold nanospheres (GNSs). The major findings of this study include superior electro-optical properties such as threshold voltage reduction by around 24%. The fall time is reduced by 11.50, 30.33, 49.33, and 63.17% respectively, and rotational viscosity is reduced by 13.86, 32.77, 36.97, and 49.58% for 5.0 x 1011, 5.0x 1012, 2.5x 1013, and 5.0x 1013number of GNS-blended liquid crystal (LC) cells. The increased UV absorbance and greatly enhanced luminescence properties have been attributed to surface plasmon resonance near the surface of GNSs and AIE effect risen due to agglomeration of the capping agent with the NLC molecules respectively, and these characteristics make them suitable for new-age display applications.
