文摘

Ga- and In-doped ZnO nanorods were prepared by hydrothermal method and annealed in diluted hydrogen atmosphere. Dramatically enhanced ultraviolet and suppressed visible emissions are demonstrated in these samples under ultraviolet or X-ray excitation. An intense superfast ultraviolet luminescence is achieved in vertically aligned ZnO:Ga nanorod arrays.
