Zinc oxide and indium-doped ZnO nano-films are prepared by two-step method on the quartz glass substrate. The growth orientation along c-axis of ZnO nano rods is changed by indium doping and with the increase of indium proportion, the orientation along (101) plane increase. The structure changes from prism-like nano rods to nanofilms due to the different indium proportion. New energy levels are introduce into ZnO causing a blue shift in the green emission region and more oxygen vacancies that results a better blue emission at 404 nm.
