T1 EFFECT OF SILVER NANOPARTICLES ON THE FLUORESCENCE INTENSITY OF RHODAMINE 6G AND SULFORHODAMINE 101 JF Telecommunications and Radio Engineering JO TRE YR 2016 FD 2016-10-26 VO 75 IS 11 SP 1001 OP 1008 K1 laser dye K1 nanoparticle K1 plasmon resonance K1 fluorescence AB Recently the trend connected with creation of new effective lasants representing the composites made of dye molecules and nanostructures of noble metals has been developing very rapidly. It is known that adding the nanoparticles of metals to the active media can be used for improving the media emission characteristics. Thus, for realization of this possibility it is necessary to research the nature of component interaction for each specific combination. In this paper, the dependence of fluorescence intensity of Rhodamine 6G and Sulforhodamine 101 liquid solutions on concentration of silver nanoparticles with a radius ~(32 ±5) nm is investigated at different frequencies of exciting radiation. It was determined that the increase of the nanocomponent concentration increases fluorescence intensity of both dyes. It is shown that the fluorescence intensity increases when the wavelength of exciting radiation approaches the maximum of nanoparticle plasmon resonance range. Basing on the received dependences, the conclusion is drawn on existence of nanocomponent optimum concentration, exceeding of which will lead to suppression of fluorescence due to the increase of probability of non-radiative deactivation of molecules excited states PB Begell House LK https://www.dl.begellhouse.com/journals/0632a9d54950b268,7502cc3b0b902a7f,4db43fdd27ed15b3.html
