Herein,　we　presented　the　low-dimensional　mechanical-exfoliated　growth　of　hexagonal　ZnO　nanorods.　The　structural,　morphological　and　optical　properties　have　been　investigated.　The　hexagonal　wurtzite　structure　has　been　confirmed　via　X-ray　diffraction　graphs　showing　the　(002)　preferred　orientation.　The　rod-like　hexagonal　structure　has　been　revealed　in　the　Field-emission　Scanning　electron　microscopy　(FE-SEM)　and　High-resolution　Transmission　Electron　Microscopy　(HR-TEM)　analysis.　Threefold　enhancement　in　near-band-edge　(NBE)　emission　of　photoluminescence　spectra　has　been　achieved　in　low-dimensional　ZnO　nanorods　(NRs)　without　any　doping.　This　paves　new　ways　for　low-dimensional　semiconductors　in　order　to　fabricate　high-efficient　luminescence　devices.
