摘要

利用真空热蒸发的方法，在云母片上制备分子层数可控的锌卟啉（ZnTPP）分子薄膜. 随着分子层数的增多，ZnTPP薄膜的光致荧光（Photoluminescence，PL）光谱从单体特征渐变为二聚体特征；原子力显微镜（Atomic Force Microscope, AFM）的图像中， ZnTPP分子团簇成纳米尺度的岛状结构，非真空环境导致纳米岛进一步聚集，从而使二聚体特征峰荧光强度激增；样品荧光寿命表明在非真空环境下分子的二聚体衰减通道比例显著增加.

Abstract

Zinc tetraphenylporphyrin (ZnTPP) film on mica was prepared by vacuum thermal evaporation，and the thickness could be calibrated by single molecular layer. The photoluminescence (PL) spectra of ZnTPP film on mica gradually changed from the spectra of monomer to that of dimer as the number of molecule layers increasing. The atomic force microscopy (AFM) image showed that ZnTPP molecules on the mica surface were clustered into nanoislands. The nanoislands were further aggregated in nonvacuum environment, which might enhance the intensity of dimer fluorescence. Fluorescence lifetime showed that the decay channel ratio of dimer increased significantly in non vacuum environment.

Key words： zinc tetraphenylporphyrin (ZnTPP); fluorescence enhancement; fluorescence lifetime
