  1. We use fuzzy mathematical morphology to remove noise and dust which can lower noise successfully and also make up a loss of intensity caused by fluorescence blench. to acquire the target region, we purpose automatic gridding method based on image segmentation for image with irregular spots, it ' s segmentation through threshold. this method is presented simply and fast

    在網中,本文針對信號點不規則的元圖像提出了基於圖像分割的自動定法? ?閾值分割,該法簡單快速,但對于光密度分佈不均勻的信號點,可能會去掉部分微信號,降低了計算的準確性。
  2. 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,一面是zno顆粒尺寸的減少,帶間的激子發射峰越來越直至猝滅,另一面主要是與zno中的o空有關,由深能級復合發光引起紅光發射。
