  1. The transmission spectra and reflectance spectra of the pc shift systematically with the spheres size, providing evidence of photonic crystal effects. photoluminescence measurements show efficient emission of the zno photonic crystals in the uv as well as a defect emission band at longer wavelength

    利用透射光及反射光研究了影響zno光子體的光子禁的工藝參數;利用x射線衍射儀分析了zno光子體的和取向能;利用熒光分光光度計,研究了不同前處理溫度下的zno光子體的光致發光
  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質進行了分析和研究,果表明:納米構zno薄膜的紫外發光來源於間激子的輻射復合發光, pl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,使薄膜的有效隙增寬; zno薄膜的紅色發光,一方面是zno顆粒尺寸的減少,間的激子發射峰越來越弱直至猝滅,另一方面主要是與zno格中的o空位有關,由深能級復合發光引起紅光發射。
