N2 - A tungsten plate was set on a one-plate electrode in RF plasma, using parallel plates in a mixed gas of argon (9.75Torr) and oxygen (0.25Torr). Zn smoke was introduced into the plasma field. W atoms were doped in the ZnO smoke formation field in the RF plasma system. The resulting particles with a size of 30nm were identified to be hexagonal ZnO particles. The collected particles changed from white to yellow, i.e., W atoms were doped into ZnO particles. The image of the (0001) lattice, which is the forbidden reflection, appeared predominantly in the W-doped ZnO particle. Furthermore, by optical measurement, it was found that the existence of W atoms can control the recombination radiation due to the exciton. On the basis of high-resolution transmission electron microscopic images, the doped W positions are discussed as being in the commensurate configuration of W atoms in the ZnO crystal at positions equivalent to those in the cubic anti-fluoride structure.
