Formation and optical properties of thin and wide tin-doped ZnO nanobelts

Thin and wide ZnO nanobelts doped with 5 atom % tin have been achieved under different flowing atmosphere. Photoluminescence measurements show a blue shift in the near band edge (NBE) emission spectrum compared to a bulk single crystal of ZnO and the intensity ratio of the NBE to the green emission of these Sn-doped ZnO nanobelts can be controlled by altering the flowing atmosphere.
