Abstract

An individual ZnO self-organized microneedle was fabricated from ZnO and graphite powder by vapor-phase transport. The lattice phase

morphology and photoluminescence property of the sample were characterized by XRD

SEM and PL. respectively

the result indicated that this product is wurtzite ZnO microneedle with hexagonal cross-section and has similar UV spontaneous and stimulated emission property comparing with other kinds of linear ZnO microstructure. Furthermore

under excitation of a femtosecond pulse laser with 800 nm wavelength

the UV laser with narrow linewidth from the sample was observed.
