| 20090281265 | Nanocrystal-polydimethylsiloxane composite and preparation method thereof - Disclosed herein are a nanocrystal-polydimethylsiloxane composite and a method for preparing the same. More specifically, provided are a nanocrystal-polydimethylsiloxane composite in which one or more polydimethylsiloxane derivatives having urea cross-links are bound to the surface of a nanocrystal, and a method for preparing the same. The nanocrystal-polydimethylsiloxane composite comprises optically transparent polydimethylsiloxane with remarkably high durability, thus imparting improved luminescence efficiency and product reliability to various electronic devices, when applied as a luminescent material to the electronic devices. | 11-12-2009 |
