Reinot, JM Hayes, KR Kalli, LC Hartmann, Lille, GJ (2002), Journal of Luminescence, vol. 12, pp 323-328. = 612.5 nm and fluorescence of the dye added to Ag ratio of 1.07 (PN) contrast (black curve) increases with the proportion of the fluorescence of only 5% of the peak? Introduction Properties of the dye laser is the most powerful band tunability of laser therapy, which has many applications in many areas. If not, the metal (PN) is very close to close to the fluorophore, is the end of the luminescence by radiation decay of excited molecules as a result of the energy-transfer dye molecules of money (PN) to increase, and when the metal (PN) in a distance, are the increase in luminescence is observed due to a fall in the distribution of radiation is not (10). 3rd Mr. Grabber is used to the spectra of fluorescence in PC software to analyze written specifically for the analysis of the wavelength, as shown in Figure 2 Figure 2 Schematic spectroscopy system and the experience requirement. Thereafter, 4 ml of NaOH (1%) was added to stirred under reflux for 30 minutes and then cooled to room temperature. 19, No. These are important factors affecting the strength of the fluorescence, the size and shape (PN), the direction of the ink on the surface dipole (PN) is normal, overlapping absorption and emission bands of the dye with the metal plasmon band and the number of radioactive decay and quantum yield (Q), fluorescent molecules (5, 11). II samples and experimental settings Experimentally, the use of dyes Rh-101, molecular weight 591.06 g, which appears as a green continuous wave absorption of 568 nm when in absolute ethanol (99.9%), respectively. 13. AgNO3 (5 mg) in EtOH (100 ml) in a reflux condenser and stirring for 15 minutes. Since facilitate the affinity of the dye molecules with silver nanoparticles, the mechanism of electron transfer and improve the profession. 4, p. 741-746. Area. Figure 4 Relationship between the percentage of the total AG and fluorescence. V. The concentration of the dye solution is chosen 4.10 m / L. Nanoparticles are prepared by reduction of AgNO3 together pyrrolidone in ethanol. Silver and Gold (PN) is in color and more popular because of the plasmon resonance frequency in the visible range, which coincides with the absorption and emission bands of these dyes. Figure 5 The relationship between Ag and the overall percentage change in wavelength. It can be also used to be industrial pollution by absorption (DIAL), differential lidar technique (2) controlled. At the same time, the addition of Ag (PN) for dilution of the dye Rh-101 concentration of 5 * 5.10 M / L ratio of 1:07 with money for a mixture of dyes, the intensity of the fluorescent dye only 5% increase and changes in wavelength range is only 2.5 nm are achieved, resulting in a low dependence on the percentage of Ag in the solution because it reduces the density of the diluted fluorescent dye for links to Ag nanoparticles that do increases the intensity of fluorescent dye, as shown in Figure 1 , whereby the strength is limited. Fluorescence can be a better field of surface plasmon-metal nanostructures associated improvement, while changes in the fluorescence spectra due to the overlap of the electronic transition will transition metal nanoparticles and molecular dye molecules. 52, No. 889, pp 383-393. Between the two nitrogen atoms, is one of them and more elektrododatnimi preferably silver nanoparticles can be combined silver nanoparticles, dyes, complex form. 12th S. Shah, M. Hammond, RN Zare (2005), and Chemical Biology, vol. When the dye solution is diluted to a concentration of 5 x 10-5 M / L and the Ar-ion laser pumping and the addition of Ag (PN) for coloring the solution so that the addition of Ag 1.07, mixed color, was the recorded fluorescence emission intensity, as shown in Fig. For example, using laser-induced fluorescence (LIF) technique, the effect of the concentration of rhodamine B in ethanol diluted laser can be designed so that the intensity of the fluorescence emission of rhodamine B in size and moves on a wave of mergers (3 ). Leave after NaOH (1%, 0.5 ml) and continue to cook for 30 minutes. Science., Vol 31, No.
