Abstract
| - Direct templating with lyotropic liquid crystalline phases of nonionic surfactants has nowbeen extended to fabricate mesoporous crystalline oxide semiconductors. ZnO and Cu2O filmshave been prepared on ITO-covered glass substrates by electrochemical deposition fromlyotropic liquid crystalline phases with polyoxyethylene surfactant. The templates and thefilms are characterized by polarized-light optical microscopy (POM), low-angle and wide-angle X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electronmicroscopy (TEM), and UV−vis light absorption spectroscopy.
- Mesoporous crystalline oxide semiconductor ZnO and Cu2O films with hexagonal structure have been prepared from the liquid crystalline phases of non-ionic surfactant via electrochemical deposition. The nanostructured films are direct casts of the structure of the lyotropic phases used to template the deposition, which is confirmed by polarized-light optical microscopy and low-angle X-ray diffraction.
