Abstract
ZnO tubes with diameters ranging from tens of nanometers to several microns were prepared via hydrothermal reactions using surfactants as structure-directing agents. All tubular ZnO materials are indexed to a hexagonal structure of wurtzite. The room-temperature photoluminescence spectra of ZnO tubes reveal a strong UV emission at around 387 nm and broad and a relative weak visible emission with main peak identified at 510-520 nm, depending on the size of ZnO tubes.
