Enhanced Out-Coupling of OLEDs Using Microlens arrays Fabricated with Irregular 3D Colloidal Arrays |
| 초록 |
Recently, for the benefit of high luminescence, microlens arrays for organic light-emitting diodes (OLEDs) have been studied in solid-state lighting field. However, microlens arrays have been generally fabricated with an ordered structure leading to an optical interference effect, which causes that a spectrum of devices with microlens arrays is different from that of standard devices. In this study, in order to overcome the unexpected problem, templates for the fabrication of microlens arrays were prepared with irregular colloidal arrays which are bimodal mixture of polystyrene particles. It was shown that the irregular microlens arrays greatly minimize the optical interference and maintain the original spectrum. |
