    摘要: 本研究利用物理氣相蒸鍍法將銅鈦花青(Copper Phthalocyanine, CuPc) 蒸鍍在玻璃基板、金基質面以及電極上,藉由基板溫度的改變來製備薄膜,並利用X 光繞射法(XRD)及掃描式電子顯微鏡(SEM)分析其薄膜晶相及表面結構,並探討其對二氧化氮氣體感測特性的影響。實驗結果顯示CuPc 的晶相為β相結晶,且不受基板溫度提高而改變,但其表面形態則因
    基板溫度的提高而由細晶粒形態變為線狀紋路,再變為鬚晶。基板溫度對氣體感測的影響,在基板溫度100℃時有最大的靈敏度。基板溫度提高至150℃後,因為鬚晶結構較不緻密,氣體脫附較易而使得回復時間縮短。
    Copper phthalocyanine (CuPc) was vacuumdeposited onto substrates of glass, gold and electrode to study the effects of substrate temperature on the film structure. The CuPc films were characterize by the X-ray diffraction (XRD) and Scanning electron microscopy (SEM), and were related to the gas sensing properties to NO2.
    The results show that CuPc films have a â form structure, which is independent to the substrate temperature. However, when the substrate temperature is elevated gradually, the film morphology varies from a fine-grain crystal to fiber-like, and then to a whisker structure. The film prepared at 100 oC has a highest sensitivity to NO2. But due to the loosely packed characteristic
    of whisker structure, the film prepared at elevated temperature has a fast recovery time.
