Luminescence property of nano-flower-like CuCl2 film based on AAO template

One novel kind of nano-flower-like film was firstly fabricated with the direct deposition method, that was, the CuCl22H2O aqueous solution was deposited on the top surface of porous anodic aluminum oxide(AAO) film. The morphology of this nano-flower-like membrane was investigated by the field emission scanning electron microscopy, and the constituent parts were analyzed with the X-ray photoelectron spectroscopy, all the results demonstrated that nanoflower-like film was CuCl2. Then, the characteristic photo luminescence spectra of the AAO film coated with nano-flower-like CuCl2 membrane were measured at room temperature. Results show that the position center of excitation is 290 nm and the emission center is 415 nm, these data are the same as the values of AAO film; however, it is excited that the intensity of luminescence increased significantly,from 127 cd to 183 cd.Furthermore, comparing with the excitation and emission spectra of CuCl2 powder and AAO film, the reason that improving the luminous intensity of the AAO film coated nanoflowerlike membrane is the morphology of CuCl2 nano-structures.
