Abstract:

Honeycomb-like films of basic zinc carbonate were successfully prepared on FTO (SnO2: F) conductive glass using bovine serum albumin (BSA) as a template at room temperature. After low-temperature annealing, a high-specific-surface-area porous ZnO film with excellent electron mobility was obtained. The surface morphology, crystallization performance, and photoluminescence characteristics of basic zinc carbonate thin films and annealed ZnO thin film were analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), photoluminescence spectroscopy (PL) and UV-Visible spectroscopy (UV-vis). By comparing with those samples prepared without any protein, it was determined that the complexation between BSA molecules and Zn2+ ions was the primary factor in the synthesis of porous films of basic zinc carbonate. The experimental results showed that the ZnO thin film samples prepared with this method had high specific surface area and broadband luminescence characteristics in the near ultraviolet range.
