英文摘要	National Natural Science Foundation of China [10875025, 20803007]; Fundamental Research Funds for Central Universities of China [DC12010116, DC13010106]; Program for Liaoning Excellent Talents in University [LJQ20l3128]; Low-pressure dielectric barrier discharge (DBD) TiCl4/O-2 and N-2 plasmas have been used to deposit titanium oxide films at different power supply driving frequencies. A home-made large area low pressure DBD reactor was applied, characterized by the simplicity of the experimental set-up and a low consumption of feed gas and electric power, as well as being easy to operate. Atomic force microscopy, scanning electron microscopy, energy dispersive spectroscopy, and contact angle measurements have been used to characterize the deposited films. Experimental results show all deposited films are uniform and hydrophilic with a contact angle of about 15 degrees. Compared to titanium oxide films deposited in TiCl4/O-2 gas mixtures, those in TiCl4/O-2/N-2 gas mixtures are much more stable. The contact angle of titanium oxide films in TiCl4/O-2/N-2 gas mixtures with the addition of 50% N-2 and 20% TiCl4 is still smaller than 20 degrees, while that of undoped titanium oxide films is larger than 640 when they are measured after one week. The low-pressure TiCl4/O-2 plasmas consist of pulsed glow-like discharges with peak widths of several microseconds, which leads to the uniform deposition of titanium oxide films. Increasing a film thickness over several hundreds of nm leads to the film's fragmentation due to the over-high film stress. Optical emission spectra (OES) of TiCl4/O-2 DBD plasmas at various power supply driving frequencies are presented.
