Abstract: | We have manufactured highly efficient OLED devices fabricated on chemically etched glass substrates. The external quantum efficiency of the OLED devices with the etched glass substrates was increased by 5-27% in comparison with the reference flat glass substrate. Surface morphology, such as indented patterns, significantly affected the external luminance efficiency. A clean surface and the presence of smooth bent edges of indented patterns were found to be important for improving the external luminous efficacy. |
