インクジェット印刷されたマイクロディスクを用いた有機発光ダイオードの作製

抄録

Microdisk cavities with high Q-factor and small mode volume can be expected for improvement in luminous efficiency of organic light-emitting diode (OLED) by fabricating OLED into microdisk. As a fabrication method to form microdisk into OLED structure, we previously proposed the ink-jet printing method, which can easily fabricate organic microdisks. However, electric field concentration caused by steric microdisk structure might break OLED. In this study, we demonstrated a fabrication of OLED on the ink-jet printed microdisk cavity.
