Annealing Temperature Effects on the Optical Properties of MnO2: Cu Nanostructured Thin Films

   In this work, the effect of annealing temperature on the microstructure, morphology, and optical properties of Cu-doped nanostructured MnO2 thin films were studied. The thin films were prepared by sol-gel spin-coating technique on glass substrates and annealed in the air ambient at 300, 350, 400 and 450 °C temperatures. The structural, morphological and optical properties of t...

Ultra-sensitive Absorption Diagnostics of Thin Films for High-power Laser Interference Coatings

The goal of this project was to demonstrate a simple method to measure absorption loss in thin dielectrics films, in particular in multilayer coatings for high power lasers in which very low absorption losses are required. The absorption characterization method is a photo-thermal technique based on thermal lensing. The method measures the defocusing of an incident probe beam caused by a thermal...

Simulation of Fabrication toward High Quality Thin Films for Robotic Applications by Ionized Cluster Beam Deposition

The most commonly used method for the production of thin films is based on deposition of atoms or molecules onto a solid surface. One of the suitable method is to produce high quality metallic, semiconductor and organic thin film is Ionized cluster beam deposition (ICBD), which are used in electronic, robotic, optical, optoelectronic devices. Many important factors such as cluster size, cluster...
