The Deposition Methods of CsI and Ni Tubes in the AAO Template

Abstract:

This paper discussed the fabrication of cesium iodide (CsI) and nickel (Ni) tubes in the anodic aluminum oxide (AAO, Al2O3) template by dropping-drying, electroless deposition, and anodization processes. The CsI dopes with Tl as scintillator can converts incident X-ray into visible light with very high conversion efficiency of optical photons. The CsI compound is so soft and extremely hygroscopic, it is very difficult to polish to obtain a smooth and optical flat plane. However, the nano-scale flat plane can be achieved when CsI was deposited in AAO template. The ionic compound of CsI can dissolve in water to form I- and Cs+. And, I- and Cs+ can absorb on AAO to form crystalline CsI after removing or drying water. Because CsI has a good wetting adhesion with AAO CsI can easily form nanoparticles and further thin film on AAO wall.
