【摘要】：采用磁控濺射法在透明玻璃基底上制備50nm厚的ZnO種子層,利用水熱法在ZnO種子層上生長厚度大約為1 000nm左右的ZnO:Cd納米棒薄膜,通過SEM,XRD對其形態(tài)和晶體結(jié)構(gòu)進(jìn)行分析。結(jié)果表明:該薄膜是由沿C軸方向生長,呈六角纖鋅礦結(jié)構(gòu)的ZnO:Cd納米棒陣列組成,并研究了薄膜型光學(xué)氣敏傳感器對氫氣的光學(xué)敏感特性,結(jié)果表明:當(dāng)工作溫度為室溫時(shí),ZnO:Cd納米棒薄膜器件對濃度為500×10~(-6)的氫氣表現(xiàn)出明顯的光學(xué)敏感特性,且具有良好的可重復(fù)性。
[Abstract]:50nm thick ZnO seed layer was prepared on transparent glass substrate by magnetron sputtering. ZnO:Cd nanorod thin films with about 1 000nm thickness were grown on ZnO seed layer by hydrothermal method. The morphology and crystal structure of ZnO:Cd nanorods were analyzed by SEM. The results show that the film is composed of a hexagonal wurtzite ZnO:Cd nanorod array grown along the C-axis. The optical sensitivity of the thin film optical gas sensor to hydrogen is studied. The results show that ZnO: CD nanorod thin film devices exhibit obvious optical sensitivity and good reproducibility to hydrogen with a concentration of 500 脳 10 ~ (-1) ~ (-6) at room temperature.
