Linearly polarized photoluminescence from anisotropic perovskite nanostructures: emerging materials for display technology

Polarization is an important feature of light, which plays an important role in display technology. Anisotropic semiconductor nanostructures (nanorods, nanoplatelets) show polarized emissions. In this progress report, we summarized the recent research progress of anisotropic perovskite nanomaterials for potential liquid crystal display backlight, with focus on the fabrication and assembly. Finally, the paper points out the bright future of using perovskite nanostructures for display technology.
