The unique optical properties of quantum dot (QD) have stimulated active researches for the next generation display and illumination. Especially, it attracts great attention in high definition display because it has narrow emission band and high efficiency for replacing OLED. Even so, it is very hard to apply it for industrial products because the optical properties of QD were degraded by oxygen, heat, and moisture. Moreover, photo-stability should be guaranteed too. To enhance QD stability, previously we developed a polymeric microcapsule. Here we present a novel method for strengthening barrier and thermal properties of the microcapsule using inorganic materials. Morphology was studied by SEM and TEM. Stability of QD was checked by life test of QD-LED in terms of applying voltages. |
