Application of a ZnO nanorod layer to display retarder: dependence of the optical property on synthesis conditions

Abstract

A series of zinc oxide nanorods (ZnO NRs) were grown by chemical bath deposition and their optical properties as a retarder for display devices were investigated. The effect of the precursors, growth time, and calcination time on the morphology and the optical properties was examined. The vertically-grown ZnO NRs layer represented positive c-plate property. We simulated the antireflection property of a quasi-circular polarizer containing the ZnO NRs layer for an organic light emitting diode (OLED) display. The quasi-circular polarizer with the ZnO NRs layer showed better antireflection property than the polarizer containing no ZnO NRs layer.

Oxygen sensing with individual ZnO:Sb micro-wires: effects of temperature and light exposure on the sensitivity and stability

“…When a ZnO wire is exposed to oxygen, some oxygen atoms get adsorbed to the wire's conducting layer, thus either compensating the vacancies or interacting with H impurities and in either case significantly reducing the conductance of the wire [1,[13][14][15][16][17]. Multiple sensing schemes and materials combinations have been proposed that revolve around the ZnO surface sensitivity to ambient gases [18][19][20][21][22]. Yet, light exposure and temperature increase also affect surface oxygen atoms and cause a large increase in conductance [23][24][25].…”
