Surface passivation effect on the photoluminescence of ZnO nanorods.
TL;DR: It was confirmed that the surface states of the as-grown ZnO nanorod arrays indeed contributed to the deep level emissions and the passivation effect was confirmed by the changes of the O 1s and Zn 2p spectra.

Hetero-metal cation control of CuO nanostructures and their high catalytic performance for CO oxidation
Hongwen Huang,Liqiang Zhang,Kewei Wu,Qing Yu,Ru Chen,Hangsheng Yang,Xinsheng Peng,Zhizhen Ye +7 more
TL;DR: It was found that the effect of hetero-metal cations on the final morphology of the CuO nanostructures was the same as that of the cooling temperature, and a series of temperature-controlled experiments demonstrated this.

Fabrication and properties of p-type K doped Zn1−xMgxO thin film
Lingjie Zhang,Zunzhong Ye,J.Y. Huang,Bingjian Lu,Haiping He,Jianguo Lu,Yujing Zhang,Jie Jiang,J. Zhang,Kewei Wu,Wenqian Zhang +10 more
TL;DR: A series of K doped Zn 1− x Mg x O thin films have been prepared by pulsed laser deposition (PLD), and Hall effect measurements indicate that the films exhibit stable p-type behavior with duration of at least six months.

Metal enhanced photoluminescence from Al-capped ZnMgO films: The roles of plasmonic coupling and non-radiative recombination
TL;DR: In this article, temperature-dependent photoluminescence (PL) from ZnMgO films grown by metal-organic chemical vapor deposition was investigated, and the enhancement ratio increased from 3.5 to ∼51 when temperature decreases from room temperature to 20'K.

Ferromagnetism induced by donor-related defects in Co-doped ZnO thin films
Liqiang Zhang,Zhizhen Ye,Bin Lu,Jianguo Lu,Yinzhu Zhang,Liping Zhu,Jingyun Huang,Weiguang Zhang,Jun Huang,Jun Zhang,Jie Jiang,Kewei Wu,Zhi Xie +12 more
TL;DR: In this article, the structural, optical, electrical, and magnetic properties were studied to clarify the origin of ferromagnetism (FM) in the ZnCoO system, and the samples were annealed after growth.
