  1. The process of photoluminescence refers to the radioative recombination of electronhole pairs generated by shining high energy light on a crystal.

    光致發光過程就是高能量光子照射到晶體上之後，晶體所產生的電子一空穴對的輻射復合過程。
  2. This direct band - gap material has a large exciton binding energy ( 60mev ), which permits excitonic recombination even at room temperature. thus zno is attracting much attention as promising candidates for optoelectric applications in visible and ultraviolet regions

    它有較高的激子束縛能（常溫下為60mev ） ，使得其在室溫下可以發射紫外激光，因此作為新一代的半導體發光材料受到廣泛關注。
  3. Zno is a directed band semiconductor with a big binding energy. it has gained substantial interest because its large exiton binding energy ( 60mev ), which could lead to lasing action based exiton recombination even above room temperature, such as led, ld and so on

    Zno是一種寬禁帶的直接帶隙半導體材料，具有非常高的激子束縛能（ 60mv ） ，即使在室溫條件下激子也不會分解，因此可以被用作光發射器件，如led和ld等。
  4. The energy released by the recombination of holes and electrons was transferred to the dye, which emitted light with greatly increased efficiency

    電洞與電子結合后所放出的能量轉移至染料，使發光效率大為增加。
  5. ( 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。
  6. We also have analyzed the photoluminescence ( pl ) spectra of some zno films, it turns out that the emission of ultraviolet light comes from the radiative recombination of excitons within nano - crystal energy band - gap, and the pl peaks move to smaller wavelength because zn are substituted by fe, co, and cu, which cause the size of the film grains smaller and the effective band - gap bigger. the red emission of zno films is due to, on the one hand, decrease of the film grains size which causes the emission intensity smaller and smaller until it disappears abruptly, on the other hand, the transition of electrons from deep donor level of the oxygen vacancies to the valence band

    另外，我們還對薄膜光致發光性質進行了分析和研究，結果表明：納米結構zno薄膜的紫外發光來源於帶間激子的輻射復合發光， pl譜的帶邊發射峰發生藍移是由於fe 、 co 、 cu對zn的替代使薄膜粒子的尺寸減小，使薄膜的有效帶隙增寬； zno薄膜的紅色發光，一方面是zno顆粒尺寸的減少，帶間的激子發射峰越來越弱直至猝滅，另一方面主要是與zno晶格中的o空位有關，由深能級復合發光引起紅光發射。
  7. For each recombination of a negative and a positive charge, a quantum of electromagnetic energy is emitted in the form of a photon of light with a frequency characteristic of the semi - conductor material usually a combination of the chemical elements gallium, arsenic and phosphorus
