Abstract :
This review article summarizes briefly some important achievements of our recent research on the synthesis, optical properties and novel applications of nano-structured ZnO such as nanorods and honeycomb shaped 3-D (dimension) nano random-walls. A chemical reaction/vapor transportation deposition technique was employed to fabricate those structures on ZnO/SiO2/Si substrate without any catalyst and additive in a simple tube furnace to aim the low-cost and high qualified samples. Random laser action with strong coherent feedback at the wavelength between 375 nm-395 nm has been firstly observed under 355 nm optical excitation with threshold pumping intensity 0.38 MW/cm2 in ZnO 3-D random-wall nanostructure.
