The method to unidirectionally align semiconductor quantum rods (QRs) by the photo-induced alignment technique is disclosed, which has originally been developed for the alignment of liquid crystals. It is shown that the strategy facilitates the alignment of highly luminescent CdSe/CdS core/shell QRs in the aligned liquid crystal monomer (LCM), obtaining solid QRs in liquid crystal polymer (LCP) matrix after UV polymerization. Optical and characterization reveals QRs alignment with highly polarized emission, indicating the high order parameter. In application aspects, the microscale (down to 2 μm domain size) pattern alignments of QRs in LCP matrix show potential in photonic and security areas; the combination of QR/LCP composite film with liquid crystal technology present the new photo-emissive displays; the QR enhancement film improves both color performance (>100% NTSC) and optical efficiency (> 8%) for modern liquid crystal display applications.
