Anodized Film on Aluminum Formed in Alkaline Media Containing Alcohols

Synthesis and characterization of porous zinc oxide nano-flakes film in alkaline media

In this study, porous zinc oxide nano-flakes were successfully synthesized by anodization method on zinc substrate in a 0.025 M NaOH and 0.05 M NH4Cl solution with the voltage of 10 V at room temperature. The field emission scanning electron microscopy’s (FESEM) images show the structural evolution during 90 min of the anodization process. They also demonstrate the dependency of growth of ZnO f...

Yellow electroluminescence from sputtering synthesized aluminum nitride nanocomposite thin film containing aluminum nanocrystals

In this work, visible electroluminescence (EL) from aluminum nitride (AlN) thin film containing aluminum nanocrystals (nc-Al) prepared by a radio frequency sputtering technique is reported. The yellow EL shows a spectrum peaked at 565 nm. A linear relationship between the EL and the current transport in the nc-Al/AlN nanocomposite thin film is observed, and both the current transport and the EL...

Magnetoresistance of Nanowires Electrodeposited into Anodized Aluminum Oxide Nanochannels

Nanoporous anodized aluminum thickness optimization through pulse current mode

The purpose of this study was to optimize the thickness of anodizing Aluminum coatings processed under pulse current mode through the Design of Experiments (DOE) method. Thickness measurement, polarization and electrochemical impedance spectroscopy were employed to take Thickness and corrosion behaviors of the anodized coatings into consideration. Also, Field-emission scanning electron microsco...

Global Oxygen Detection in Water Using Luminescent Probe on Anodized Aluminum

We have developed anodized-aluminum pressure-sensitive paint (AA-PSP) as a global oxygen sensor in water. Platinum (II) meso-tetra(pentafluorophenyl)porphine is selected as a luminophore based on a dipping deposition study. The developed AA-PSP is characterized using water calibration setup by controlling dissolved oxygen concentration. It is shown that AA-PSP yields 4.0% change in luminescence...
