     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.
