recombination rate 解釋
復合率
  • recombination : 沖調;復水
  • rate : n 1 比率,率;速度,進度;程度;(鐘的快慢)差率。2 價格;行市,行情;估價,評價;費,費用,運費...
  1. The total rate at which recombination is occurring is certainly proportional to the number of electrons times the number of ions.

    產生復合的總比率一定正比于電子數和離子數的乘積。
  2. ( 4 ) the photocatalytic activity tio2 - fe2o3 composite film is superior to that of pure tio2 film as the content of fe2o3 is lower which attribute to the separation of photo - induced carriers between in the semiconductors having different energy level. the photocatalytic activity is the best as the mole content of fe2o3 is about 0. 5 %, and the hydrophilicity is the best as the mole content of fe2o3 is about 0. 05 ~ 0. 1 %. but the photocatalytic activity and hydrophilicity of the stromatolith and the composite stromatolith films of tio2 and fe2o3 are not good because the recombination rate of photo - induce

    9296昆明理工大學博士學位論文摘要( 3 ) ti02薄膜厚度的計算公式: d =入又22 ( nz兄,一n又2 ) 6 、針對自清潔玻璃中試生產中的工藝特點及在實際使用中的性能要求,研究並初步獲得了以玻璃為襯底的自清潔薄膜的中試制備工藝,以及自清潔玻璃的物理性能、親水特性、化學與環境穩定性的表徵與評價方法。
  3. Because of the anatase ' s broad eg ( 3. 2ev ), the absorption thresholds correspond to 380nm for the tio2. consequently, only the ultraviolet fraction of the solar irradiation can be active in the photoexcitation processes using pure tio2 solid. the high recombination rate of charge carrier and low efficiency of quantization are also the deficiencies of pure tio2

    由於tio _ 2的帶隙較寬(約3 . 2ev ) ,半導體的光吸收波長范圍窄(主要在紫外區) ,故其太陽能的利用效率低,且還存在半導體載流子的復合率高,量子化效率低等缺陷。
  4. Volume recombination rate

    體積復合率
  5. Moreover, the sio2 / tio2 composite thin film showed the lowest pl intensity due to a decrease in the recombination rate of photo - generated electrons and holes under uv light irradiation, which further confirmed the film with the highest photocatalytic activity at 700 c. when the calcination temperature was higher than 700 c, the decrease in photocatalytic activity was due to the formation of rutile and the sintering and growth of tio2 crystallites resulting in the decrease of surface area

    同時,此時sio _ 2 / tio _ 2復合薄膜的熒光光譜顯示最低的熒光強度,這表明此時薄膜中的光生電子和空穴的復合速率最低,因而更有利於物質的光催化降解。當熱處理溫度高於700時,武漢理工大學碩士學位論文薄膜的光催化活性下降,這是由於薄膜中晶相二氧化欽的燒結和成長導致樣品的表面積下降以及金紅石相的形成。
