  1. The electronic temperature, intensities of all lines and continuous spectra gradually increased with the increment of laser energy, and they got to maximum at different laser energy. our results of copper and aluminum show that there are possibly different thresholds of laser energy to electronic temperature and intensities of emission spectra of laser ablated plasma. at the different environmental gas pressure, spatial emission intensity distribution is explained by the competition among " heat reservoir effect ", " confined effect " and " s hadow effect "

    認為cu等離體羽的發光機制是由電與粒的碰撞傳能、電與離形成的;隨光能量的增加, cu等離體特徵(分立譜) 、連續背景(連續譜) 、電溫度都出現最大值;結對al的實驗結果說明:光燒蝕金屬產生的等離體,其特徵、連續、電溫度可能都存在一定的能量閾值;背景氣壓對光燒蝕等離體譜線的影響,其機理可以認為是「熱庫效應」 、 「約束效應」及「陰影效應」相互競爭的綜結果。
  2. The isoelectronic system of gap : n has been investigated extensively in the dilute limit since 1965. thomas et al identified that a series of sharp emission lines in gap : n were due to the recombinations of excitons bound to either isolated nitrogen centers or various nitrogen pair centers

    這些譜線來自於等電雜質n形成的束縛態(孤立n中心和nn _ i對)產生的零聲線及其聲伴線。
  3. By using the multi - configuration dirac - fock ( mcdf ) method, the effects of relaxation and correlation on the transition energies and probabilities of electric - dipole allowed ( el ) resonance and intercombination transitions for 2p53s3 - 2p6 in neutral neon have been systematically studied firstly. and the results of the transition energies and probabilities ( lifetimes ) in length and velocity gauge have been presented. during the calculation, in order to consider the rearrangement effects of the bound - state density and some important correlations, the asfs of transition initial - and final - states were divided according to their angular - momentum and parity and calculated, and different number of csfs were included in the expansion of asfs

    本文利用多組態dirac - fork ( mcdf )理論方法,通過對躍遷初、末態電波函數的獨立計算以及在原態波函數的展開中考慮不同數量的組態波函數,系統地研究了弛豫和相關效應對中性ne原2p ~ 53s ~ ( 1 . 3 ) p _ 1 ~ o - 2p ~ 6 ~ 1s _ 0電偶極共振和躍遷的能量以及躍遷幾率的影響,給出了長度和速度兩種不同規范下發態的能量和壽命;以中性ne原的研究為基礎,進一步研究了類ne等電系列離( z = 11 - 18 )較低的發組態2p ~ 53s和基組態2p ~ 6的能級結構以及各能級間的躍遷特性。

  5. Compared to gan, which is one of the most successful wide - band semiconductor materials at present, zno is promising : high - quality zno with very low defect densities can be synthesized at much lower temperature than gan ; zno can emits light with shorter wavelength than blue light emission from gan ; zno has higher excitonic binding energy ( ~ 60mev for zno, 25mev for gan ), which promises strong photoluminescence from bound excitonic emissions at room temperature ; meanwhile, homogeneous bulk zno is available

    和gan相比, zno薄膜具有生長溫度低,能高( zno : 60mev , gan : 21 25mev ) ,受閾值較低,能量轉換效率很高等優點。有可能實現室溫下較強的紫外受,制備出性能較好的探測器、發光二極體和光二極體等光電器件。
  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發光, pl譜的帶邊發峰發生藍移是由於fe 、 co 、 cu對zn的替代使薄膜粒的尺寸減小,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,由深能級發光引起紅光發
