FIG. 1.

Extinction spectra of the Ag NPs deposited on SiO2 glass substrates using a layer-by-layer method. The mean particle size in samples-A, B, and C is different from each other. Inset shows a TEM image for a typical Ag NP prepared. The image was taken by dispersing Ag NPs onto a Cu grid.

(a) Emission spectra of the sample-A below (denoted by a dotted curve) and above (a solid curve) the threshold. The inset shows the output intensity of the emission peak as a function of pump energy for sample-A (solid circles) and a reference sample without NPs (open circles). FWHM of the emission spectra for sample-A is plotted in the right ordinate (solid squares). (b) Emission spectra above the threshold for sample-A (a solid curve), sample-B (dashed), and sample-C (dotted). The spectrum of a reference sample without NPs is also shown by a gray dashed curve. (c) Emission spectra of the sample containing SiO2 NPs (60 nm diameter) below (denoted by a dotted curve) and above (a solid curve) the threshold. The inset shows the output intensity of the emission peak (left ordinate, circles) and FWHM (right, squares) as a function of pump energy.

FIG. 3.

Relation between the wavelength of the ASE and that of the LSPR. Solid circles indicate the samples with Ag NPs, and crosses correspond to the samples containing Ag core-SiO2 shell NPs.
