    摘要:

    利用超聲霧化熱解技術(shù) (USP) 在不同溫度的電氣石和玻璃襯底上生長ZnO納米片狀薄膜。結(jié)構(gòu)研究表明晶體為六方纖鋅礦多晶結(jié)構(gòu)。襯底溫度越高,Raman特征峰越強,XRD結(jié)果給出(002)優(yōu)勢定向越明顯,晶體結(jié)晶性能越好,晶粒尺寸越大。SEM圖像顯示片狀ZnO晶體沿平行襯底方向疊加形成花狀晶柱的微觀形貌,沉積溫度越高,晶柱寬度越大。UV-Vis表明電氣石襯底上ZnO吸收峰強度高于玻璃襯底,最大吸收峰位置發(fā)生紅移,高溫下移動更大。

    Abstract:

    ZnO nanosheet thin films were obtained by the ultrasonic spray pyrolysis technique (USP) on tourmaline and glass substrates at different deposition temperature. Structural studies suggested that ZnO crystals were polycrystalline with hexagonal wurtzite structure. The intensity of the characteristic Raman peak, and the (002) preferential orientation, the degree of crystallinity, the grain size achieved by the XRD results were significantly increased with the elevation of the substrate temperature. SEM images showed that the ZnO nanoplates laminated in parallel to the substrate and assembled to the flower-like column morphology, ZnO nano crystals had larger lamellae sizes and wider crystalline columns at higher temperature. UV-Vis measurement confirmed the maximum absorption peak of the ZnO films on the tourmalines had more red shifts and stronger intensities than that on the glass substrates, and relatively greater wavelength shifts under higher substrate temperature were also observed.
