技術摘要 / Our Technology: |
本發明係提供一種微細顆粒組成之光閘晶體之表面奈米鍍層之方法,其可避免布朗運動及凡得瓦力之聚結作用,控制奈米顆粒吸附在微細陶瓷氧化物顆粒鍍層,可以將奈米級氧化鈦均勻鍍在氧化矽顆粒表面。此方法在水基溶液內實施,所得到的鍍層厚度可以控制在5奈米至數十奈米之間,厚度均勻。鍍層後之複合顆粒經過煆燒處理,可以得到具有均勻奈米顆粒表層之複合顆粒,此複合顆粒可經組合製作光閘晶體。此外,本發明亦揭露一種將氧化矽光閘晶體鍍上一氧化鈦層之方法。
This invention discloses a coating method to apply a layer of nano-particles absorbed on submicron ceramic oxide particles, which can prevent the agglomeration of nano-particles by the effects of Brownian motion and van der Waals force. Using this method, nano-sized titania can be uniformly coated on the surface of silica. This method is conducted in an aqueous solution and able to fabricate a coating layer in a controlled thickness between 5 to tens nm. After calcination, the coated particles can be assembled to form a photonic bandgap crystal. This invention also discloses a coating method to apply a uniform nano TiO2 -coating layer on the 8102 photonic band gap crystals.
