Estimation of Theoretical Models of Photophysical Processes for Fluorescein Laser Dye with Ag Nanoparticles

Abstract

In this study, a novel theoretical method for the absorption and fluorescence spectral estimations has been presented. These estimations have been based on experimental measurements of absorption and fluorescence spectra for the solutions of Fluorescein laser dye with Silver (Ag) nanoparticles in distilled water. The used concentration was (1x10-5 M) for Fluorescein dye, while the mass amounts were (0.003g, 0.005g, 0.0065g, 0.008g and 0.0085g) for Silver nanoparticles. A spectral absorption enhancement was detected in the case of increased Silver nanoparticle masses, which specify that the doped Fluorescein dye with Ag nanoparticles has an important effect on the dye absorption spectra. On the other hand, each fluorescence emission spectrum for the dye has quenched as Ag nanoparticle's mass amounts have increased. The related amounts of mass increase as a consequence of Förster resonance energy transfer (FRET). The novel approach of theoretical estimations has been based on curve fitting using Logistic Power Peak (LPP) function to estimate theoretical models for the absorption and fluorescence spectra of these samples. These rated models have excellent matching profiles with the experimental profiles so that the estimated models can replace the experimental measurements.
