Up-Conversion Mechanisms and Application of Rare Earth-Doped ZnO

Zinc oxide (ZnO) the film is a new type of transparent conductive oxides (TCO) material; it has a green environmental application prospect and hopeful to be substitution of indium tin oxide, so it has been the research focus of TCO materials. The rare earth ion like Yb3+, and Ho3+, Er3+shall be applied to satisfy the up-conversion function, and rare earth elements doped ZnO transparent conductive films will prepared. The play is to study the mechanism of up-conversion and energy transitions that the rare earth ions in the ZnO transparent conductive film. Through the theoretical analysis with the performance of the zinc oxide thin films explore optimization scheme, and aim to prepare out doped-ZnO and transparent conductive film that have both excellent photoelectric performance and up-conversion function. This new type of ZnO transparent conductive film with up-conversion function, it will have important theoretical significance in production of green environment materials and good application prospect in the field of sole cells, photoelectric detection luminescent device and so on.

Silver nanowire (AgNWs) transparent conductive film (TCF) is considered to be the most favorable material to replace indium tin oxide (ITO) as the next-generation transparent conductive film. However, the disadvantages of AgNWs, such as easy oxidation and high wire-wire junction resistance, dramatically limit its commercial application. In this paper, moisture treatment was adopted, and water was dripped on the surface of AgNWs film or breathed on the surface so that the surface was covered with a layer of water vapor. The morphology of silver nanowire mesh nodes is complex, and the curvature is large. According to the capillary condensation theory, water molecules preferentially condense near the geometric surface with significant curvature. The capillary force is generated, making the wire-wire junction of AgNWs mesh bond tightly, resulting in good ohmic contact. The experimental results show that AgNWs-TCF treated by moisture has better conductivity, with an average sheet resistance of 20 Ω/sq and more uniform electrical properties. The bending test and adhesion test showed that AgNWs-TCF treated by moisture still exhibited good mechanical bending resistance and environmental stability.

Conductive Film

In this paper，ZnO/PANI transparent conductive film has been prepared by in situ chemical oxidative polymerization, APS as an oxidant. The conductivity and transmittance of ZnO/PANI was measured. It has been investigated of the effects of reaction conditions and the doping component on conductivity, transmissivity and adhesion. With the increase of doping ZnO, the conductivity of ZnO/PANI transparent conductive film, transmittance and adhesion reduced. The optimal conditions is that the concentration of An, APS and PVA are 0.75 mol / L, 0.8 mol / L and 0.5wt%, respectively.
