By using a galvaostatic electrodeposition method in the ZnCl2 solution,the highly oriented ZnO nanorod array films have been successfully prepared on ITO substrate after the pretreatment with ZnO nanoparticles.And they were characterized by scanning electron microscope,X-ray diffraction and transmittance spectra.The results indicated that the ZnO nanorod arrays grew along(001) direction with an orientation perpendicular to the substrate.When the wavelength of incident was over 380 nm,the ZnO nanorod arrays showed high optical transmission of above 95%.Furthermore,the band gap became narrower.

The texturization of(100) crystalline silicon(c-Si) wafer was studied by field-emission scanning electron microscope using different kinds of etchant: sodium hydroxide,sodium carbonate and tribasic sodium phosphate.By optimizing the etching parameters,the lowest values of averaged reflectance(Rav) were obtained to be 9.70% for NaOH,9.76% for Na2CO3 and 8.63% for Na3PO4·12H2O,which is comparable to that of the wafer with textured surface covered with an anti-reflection coating of either silicon nitride or thermally grown silicon dioxide.The relation of Rav and surface morphology of textured wafer was analyzed.Moreover,special emphasis was put on the role of isopropyl alcohol(IPA) and sodium bicarbonate for texturization.It is proved that IPA …

The Fe-doped TiO2 nanotube arrays were fabricated in Fe(NO3)3-HF mixing solutions by electrochemical anodic oxidation method,and characterized by FESEM,Raman,XPS and DRS.The effect of Fe concentratiions on photoelectrochemical property of the arrays was also investigated.The diameters and lengths of Fe-doped TiO2 nanotube arrays were 50~90 nm and about 200 nm,respectively.Compared with the undoped TiO2 nanotube arrays,the absorption edge of Fe-doped TiO2 nanotube arrays appeared red shifting.The more Fe content,the larger red shifting,in addition,the photocurrent of Fe-doped TiO2 nanotube arrays increased obviously.
