技術摘要:
本發明提供一種奈米氧化鋅有機無機複合薄膜之電激發光元件,係使用旋轉塗佈技術並輔以相分離的方式,將氧化鋅奈米粒子與有機導電材料製成分層結構之有機無機複合薄膜,而此分層結構製作為電激發光元件將可使得電子電洞對在氧化鋅奈米粒子的復合機率提高,可有效實現低成本製作之藍光發光元件,並可應用於大面積製作,其應用範圍亦非常廣泛。
The present invention discloses an electroluminescent element implemented by a zinc oxide nanoparticle-containing organic-inorganic composite film. In the present invention, a spin-coating technology together with a phase-segregation technology is used to fabricate zinc oxide nanoparticles and an organic electrically-conductive material into a layered organic-inorganic composite film, and an electroluminescent element is fabricated with the layered structure, which can increase the probability of the electron-hole pair recombination in zinc oxide nanoparticles. Thereby, the present invention can realize a low-cost blue light-emitting element having a large emitting area and an extensive application field.
