Thin films of Zn1-xMnxO (x = 0.00, 0.03, 0.07, 0.10) were prepared onto glass substrates by sol-gel spin-coating technique. The structural, morphologic and optical properties of these samples were studied respectively. The XRD patterns show the thin films are all polycrystalline with hexagonal wurtzite structure and no preferred orientation. With the increase of Mn doping, the c-axis lattice constants of the samples shift towards higher values until the doping concentration reaches up to 7%. This indicates that Mn2+substituted for Zn2+of ZnO host. Moreover, the grain size decreases gradually with the increase of Mn doping content. The AFM results indicate surface roughness increases with the increase of Mn doping level. The photoluminescence spectra reveal Mn doping causes a blue shift of the UV peak. The intensity of UV emission peaks increases at the beginning and then decreases with the increase of Mn doping content.

Transparent thin films of Sn-doped ZnO (ZnO:Sn) were deposited onto silica glass substrates by the sol–gel method. The effect of different Sn doping on the crystallinity, structural, optical and electrical properties of ZnO:Sn thin films were investigated by XRD, SEM, UV-VIS spectrophotometer and four-point probe method respectively. Among all of ZnO:Sn thin films in this paper, Sn-doped with 2 at.% exhibited the best properties, the surface demonstrate an accumulative crystallization and hexagonal structure, with a high-preferential c-axis orientation, namely an average transmittance of 90% and the resistivity of 19.6 Ω·cm.

The effect of tinidazole on the zinc corrosion in 0.1mol/L KOH solution has been studied by polarization curves, electrochemical impedance spectroscopy (EIS), SEM, and weight loss measurements. It has been shown that tinidazole act as an anodic inhibitor, can effectively restrain the process of the anodic oxidation of zinc.The highest value of inhibition efficiency is 89.39% at 50mg/L concentration.
