Anisotropic nanomaterials exhibit unique properties, which allow their implementation into new enhanced optical devices. Dot-in-rods (DRs) exhibit polarized emission with high degrees of polarization (DOPs) and high quantum yields. The energy-efficient generation of polarized light is of major interest for display technologies. Aligned DR nanostructures have been reported as photoluminescent light sources for efficient LCD technologies. Aligned DR films can also find use as color converters with polarized photoluminescence.[1,2]
One of the main challenges is the alignment of DRs for their use in macroscopic devices. This contribution offers insight into the large-scale fabrication of CdSe/CdS DRs by continuous flow processes and their subsequent alignment. The produced films exhibit high DOPs in ensemble, and can be further used as polarized photoluminescent layers in color converters and electroluminescent quantum-based LEDs.
