Abstract

In this paper, hierarchical structured ZnO particles were successfully synthesized via a facile biomineralization process with the template of histidine at room temperature. Detailed microstructural characterization had been carried out using X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Role of histidine concentration in the hierarchical ZnO syntheses, including flower-type structure and mineral configuration, had been systematically investigated. Zn2+–histidine interaction was suggested to be the dominant growth factor. The room-temperature Raman spectrum of ZnO flower type revealed good crystal quality and increased Raman scattering. The PL spectrum of ZnO mineral structure showed stronger emission in a wide range of wavelengths.
