The effect of nanoparticle size on the structural, optical, and electrical properties of tungsten oxide prepared by laser ablation method

Tungsten oxide nanoparticles (WO 3 ) were successfully produced using the Pulsed Laser Ablation method in organic solvent (2-methoxyethanol) for the first time. The ablation process was carried out using a Q-switched Nd:YAG laser of 1064 nm wavelength with different numbers of pulses 100, 200, 300,...

Description
Summary:Tungsten oxide nanoparticles (WO 3 ) were successfully produced using the Pulsed Laser Ablation method in organic solvent (2-methoxyethanol) for the first time. The ablation process was carried out using a Q-switched Nd:YAG laser of 1064 nm wavelength with different numbers of pulses 100, 200, 300, and 400 to irradiate the target. The resulting tungsten oxide nanoparticles were characterized using various techniques such as infrared spectroscopy to determine the effective groups and bonding pattern, as well as studying the morphology of those nanoparticles through an atomic force microscope. The study included also to study the optical properties, calculate the optical constants, and finally study the electrical properties of nanoparticles suspended in organic solution. The study showed that the effect of the number of pulses resulted in a difference in the size of the nanoparticles, which in turn showed a clear effect on the optical and electrical properties of tungsten oxide. A new model to understand the electrical conductivity results at different grain sizes was applied in this study.
