“…The fitting result for refractive index of deionized water, i.e. 1.3317, shows a good agreement with other published values as reported by Weast et al (1978), Webb et al (1989) and Ma et al (2000) [22][23][24]. Thus, it shows that the SPR measurement can be used to determine the optical properties of the liquid sample.…”

The aim of this research is to characterize the optical properties of heavy metal ions (Hg2+, Cu2+, Pb2+ and Zn2+) using surface plasmon resonance (SPR) technique. Glass cover slips, used as substrates were coated with a 50 nm gold film using sputter coater. The measurement was carried out at room temperature using Kretchmann SPR technique. When the air medium outside the gold film is changed to heavy metal ions solution, the resonance angle shifted to the higher value for all samples of heavy metal ions solution. By our developed fitting program (using Matlab software), the experimental SPR curves were fitted to obtain the refractive index of Hg2+, Cu2+, Pb2+ and Zn2+ ions solution with different concentrations. Both the real and imaginary part of refractive index of the heavy metal ions solution increased with the concentration. The results give the basic idea such that the SPR technique could be used as an alternative optical sensor for detecting heavy metal ions in solution

“…They reported the existence of oxide layers with thicknesses of 3.15-3.35 nm on the Al films after exposure to air for 5-30 min [12]. Ma et al [13] investigated theoretically and experimentally the conditions for light-induced excitation of the surface plasmons in the Al films (20 nm) at a liquid interface in the Kretschmann configuration. They showed that the peak widths in the SPR spectra are relatively broad for Al compared with those for Ag and Au.…”

“…The SPR reflection spectra of Al films have been measured in both the Otto configuration [8][9][10] and the Kretschmann configuration [11][12][13]. The optical constants of deposited Al films [8], the reflection properties of a MgF 2 -coated Al mirror [9], the influence of surface oxide layers of Si-SiO 2 -Al structures on SPR [10], the thicknesses of the oxide layers grown on deposited Al films on silica prisms [11,12], and the conditions for light-induced excitation of SPR at an Al-liquid interface [13] have been investigated. Though these investigations give important information on the SPR phenomenon of Al films, more investigations are necessary to understand the properties of Al films as an SPR sensor element.…”

“…Among the SPR-compatible metals, Al has received much attention and many investigations gave important information on the SPR phenomenon of Al films. [10][11][12][13][14][15][16][17][18] Recently, Al/TiO 2 film has been used in SPR optical fiber sensors owing to its response in the NIR region, especially in the 1500 nm region. [19] Cu film has also been used as an SPR sensor element, [16] however, no sufficient investigations on the SPR sensing properties of the Cu film have been carried out due to its unstable chemical properties as compared to Au, Ag, and Al films.…”

A new analytical method based on the surface plasmon resonance (SPR) technique is presented, with which SPR curves for both wavelength and angular modulations can be obtained simultaneously via only a single scan of the incident angle. Using this method, the SPR responses of TiO2-coated Cu films are characterized in the wavelength range from 600 nm to 900 nm. For the first time, we determine the effective optical constants and the thicknesses of TiO2-coated Cu films using the SPR curves of wavelength modulation. The sensitivities of prism-based SPR refractive index sensors using TiO2-coated Cu films are investigated theoretically for both wavelength and angular modulations, the results show that in the case of sensitivity with wavelength modulation, TiO2-coated Cu films are not as good as the Au film, however, they are more suitable than the Au film for SPR refractive index sensors with angular modulation because a higher sensitivity can be achieved.
