Abstract

Colloidal semiconductor nanocrystals (NCs), or quantum nanostructures with various dimensions and morphologies, are excellent emerging solution-processable luminescent materials for display applications. The future of semiconductor NCs in the display market strongly relies on the development of low energy consuming devices. Replacing spherical NCs with multi-dimensional nanostructures that emit linearly or circularly polarized light with high color purity and brightness, can significantly enhance the performance and efficiency of future display devices. In this review, we highlight some recent advances of colloidal syntheses of multi-dimensional quantum nanostructures and their implementation as polarized light sources. The most representative examples are quasi-one-dimensional (q-1D) CdSe/CdS dot-in-rods with strong linearly polarized emission for liquid crystal display technologies, and two-dimensional (2D) nanoplatelets with enhanced circular dichroism signals as potential circularly polarized luminescence sources for electroluminescence applications.
