Abstract
In this work, thin films of tin oxide were synthesized by vaporizing tin oxide powder targets using a continuous CO2 laser of specific power and then deposition of the resulting vapor on glass substrates. Two films were synthesized, one of which was annealed at 550 °C for 2 h. The effect of thermal annealing on the structural and optical properties of the prepared films was investigated. The obtained results showed that thermal annealing causes changes in crystallite size related to the orientations of the crystal planes. Moreover, the appearance of the plasmon resonance peak of tin oxide particles was observed in the absorption spectrum of the as-deposited sample at 305.88 nm. This peak becomes broader and moves to 336.87 nm in the spectrum of the annealed sample.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
