Zinc oxide nanosheets are grown on FTO glasses using electrochemical deposition technique. We use Rhodamine B solution as the random laser gain medium. Optical feedback is provided by light multi-scattering from ZnO nanosheets. We observe that the random lasing emission from ZnO nanosheets is multi-mode and discrete modes appear in the emission spectrum for pumping energies larger than the threshold pumping energy. In this investigation we measure the threshold pumping energy for each of the lasing modes excited in the nanostructure. Our results also show that the random lasing emission from Zinc oxide nanosheets is not directional and furthermore it depends on the position of the sample which is pumped.
