ABSTRACT

Well-ordered metal structures, i.e. arrays of nanosized tips on silver surface for studies of the luminescence enhancement of absorbed media with rare earth ions, are used. These arrays are prepared by metal evaporation on track membranes. Basic relations determining plasmon oscillation frequencies for tip electron systems, modeled by semi-spheroidal protrusions, are presented. The impact on these frequencies by the dipole-dipole interaction developed in the tips is analyzed. Parameters of silver nanosized tips for enhancing luminescence in media with erbium ions, widely used in fiber-optical amplifiers at the 1.54 micron wavelength, are determined. Experimental samples of nanosized tip structures for spectral luminescent measurements in media with europium ions are obtained and characterized. Frequency characteristics are modeled numerically for typical tip nanosized structures by the finite difference time-domain method (FDTD). The calculations results obtained by means of the SCT Microwave Studio are compared with experimental data
