  2. When the thickness increases up to a critical value, about 30 nm, the spotty rheed pattern gradually changes to streaky pattern, and the rheed oscillation curve appears. the rheed pattern of the ultra thin lno film deposited in the relatively high oxygen pressure is streaky pattern. with pumping the oxygen pressure to the relatively low value, the streaky rheed pattern gradually changes to spotty one

    我們發現在較低的真度下,即氧分壓處於2 10 - 4pa和3 10 - 3pa之, lno中的一個o2 -將會轉移兩個電子給兩個ni3 + ,並且移動到薄膜表面形成o2被泵抽走,從而導致鈣鈦礦的垮塌,其相應的rheed圖樣呈現出清晰而明亮的點,表明表面為較為粗糙的三維島狀
  3. 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,果表明:納米zno薄膜的紫外發光來源於帶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,帶的激子發射峰越來越弱直至猝滅,另一方面主要是與zno中的o位有關,由深能級復合發光引起紅光發射。
  4. But in the moderate electric field 150 kv / cm, there is a sharp change in the configuration and charge distribution of the exciton, i. e. the exciton is directly split into an electron polaron and a hole polaron. the polarization and dissociation happen at a same time, which differs from that in conjugated polymers. and in the strong electric field 350 kv / cm, appear structural phase transition of the chain and luminescence quenching

    同時得到兩個重要的臨界電場值: 1激子解離電場ec1 ( 150kv / cm ) ,在此電場下激子發生瞬解離,成為電子型極化子和穴型極化子; 2相變電場ec2 ( 350kv / cm ) ,在ec2下二聚化開始被等距取代, ptcl絡合物鏈發生相變,並伴隨peierls能隙漸趨消失和發光猝滅的現象出現。
