“…However, this phenomenon does not exist when the radius of the particle is very small. It dues to that smaller particles will probably quench the effect since the scattering effects are dominant in large particles (r≥50nm) whereas absorption dominates for small ones (r<10nm) [11] .…”

Much attention has been paid to the semiconductor-metal phase transition in vanadium dioxide nanomaterials, accompanied with an abrupt change in its resistivity and near-infrared transmission. The phase transition and optical properties of vanadium dioxide nanoparticles were studied by the mathematical model based on the complex refractive changing with the temperature and wavelength. The optical properties of nano-array were investigated by using the discrete dipole approximation and Mie scattering theory, as well as the absorption and scattering properties of small particles. The results show that the main contribution to the optical response with variational wavelength in the infrared is from absorption cross section comparing with the scattering cross section. It is obvious that the absorption peak of metal phase occurs near 980nm. With the change of temperature, the variation of extinction coefficient is larger in the infrared region than in the visible region. The largest change of extinction coefficient occurs in the near-infrared region.The extincition coefficient is very small in the visible region and there is a maximal value in the infrared region in the nano-array.

“…In general, the band width, intensity and position of the PPR wavelength of these metallic particles vary with particle size and shape and with their surrounding matrix (Kreibig and Vollmer 1995;Beecroft and Ober 1997;Lance et al 2003). The sensitivity of the PPR frequency to small variations of these parameters can be used in various applications such as colour filters (Quinten 2000;Biswas et al 2004) sensors (Haes and Van Duyne 2002;Haes et al 2004) and all optical switching devices (Stegeman and Wright 1990).…”

Copper nanoparticles have been synthesized in polycarbonate by 75 KeV Cu -ion implantation with various doses ranging from 6⋅4 × 10 15 to 1⋅6 × 10 17 ions/cm 2 with a beam current density of 800 nA/cm 2 . The composites formed were structurally characterized using Ultraviolet-Visible (UV-Visible) absorption spectroscopy. The appearance of particle plasmon resonance peak, characteristic of copper nanoparticles at 603 nm in absorption spectra of polycarbonate implanted to a dose of 1⋅6 × 10 17 ions/cm 2 , indicates towards the formation of copper nanoparticles in polycarbonate. Transmission electron microscopy further confirms the formation of copper nanoparticles having size ~ 3⋅15 nm. The formation of copper nanoparticles in the layers carbonized by Cu -implantation has been discussed. The synthesized copper-polycarbonate nanocomposite has been found to be more conducting than polycarbonate as ascertained using current-voltage characteristics.
