ABSTRACT The ferroelectric liquid crystal (FLC) shows improvement in electro-optical properties on incorporation of Co-ZnO/ZnO core/shell (CZZ) quantum dots (QDs), which is a manifestation of better alignment for FLC molecules. A suitable amount of core/shell QDs was added into pure FLC and studied using polarising optical microscope, ferroelectric, photoluminescence (PL) and dielectric measurements. Significant increase in the order parameters (θ, PS) and PL intensity with reduced light leakage centres and dielectric loss factor are the consequences of enhanced molecular ordering of FLC molecules dispersed with CZZ QDs. FLC composites with luminescent core/shell QDs are a step forward for the improvement of low power operated highly photoluminescent FLC-based display devices. Such emissive liquid crystal displays would exhibit improved brightness, better contrast, wide viewing angle and lower operating power. Graphical abstract

Co-ZnO/ZnO核/壳量子点对铁电液晶分子取向的改进

摘要 铁电液晶 (FLC) 在掺入 Co-ZnO/ZnO 核/壳 (CZZ) 量子点 (QD) 后显示出电光性能的改善，这是 FLC 分子更好排列的表现。将适量的核/壳量子点添加到纯 FLC 中，并使用偏振光学显微镜、铁电、光致发光 (PL) 和介电测量进行研究。有序参数 (θ, PS) 和 PL 强度显着增加，同时漏光中心和介电损耗因数降低，这是由 CZZ QD 分散的 FLC 分子增强分子排序的结果。具有发光核/壳量子点的 FLC 复合材料是改进低功率操作的高光致发光 FLC 显示设备的一个进步。这种发光液晶显示器将显示出更高的亮度，更好的对比度、更宽的视角和更低的操作功率。图形概要
