摘要： Technique for large-scale manufacturing of high-efficiency light-emitting apparatuses for solid-state lighting and display applications are disclosed. The light-emission profiles of the light-emitting apparatuses may be modified through the incorporation of metasurfaces thereinto. The devices may be light-emitting diodes (LEDs), quantum-dot light-emitting diodes (QLEDs), organic light-emitting diodes (OLEDs), and passive-matrix and active-matrix OLED and QLED displays. The integrated metasurfaces are two-dimensional sub-wavelength-spaced nanostructures that enable efficient light extraction from the devices and modification of their emission profiles for desired applications. The light-emitting apparatuses may be fabricated using sheet-to-sheet, roll-to-sheet, and roll-to-roll nanoimprint lithography.
