Abstract
Metal enhanced fluorescence (MEF) is an unequaled phenomenon of metal nanoparticle surface plasmons, when light interacts with the metal nanostructures (silver nanoparticles) which result electromagnetic fields to promote the sensitivity of fluorescence. This work endeavor to study the influence of silver nanoparticles on fluorescence intensity of Fluoreseina dye by employment mixture solution with different mixing ratio. Silver nanoparticles had been manufactured by the chemical reduction method so that Ag NP layer coating had been done by hot rotation liquid method. The optical properties of the prepared samples (mixture solution of Fluoreseina dye solutions and colloidal solution with 5 minutes prepared of Ag NPs) tested by using UV-VIS absorption and Fluorescence spectrophotometer. by using AFM, SEM testes, the structure of silver nanoparticles had been estimated. the result of this work showed that adding Ag NPs colloidal to Fluoreseina dye solution help get a significant increase in the fluorescence intensity of this dye. this study results show that its significant to recent related studies in MEF.

Metal enhanced fluorescence (MEF) is the interaction of the excited state of fluorophore with the localized surface plasmons of the metal nanoparticles (MNPs) and that resulted in amplifies the radiative quantum yield and increase the fluorescence intensity of the fluorophore [5]. due to Silver nanoparticle characteristic like high reflection, suitability, and biocompatibility, its common material used for MEF applications [6]
The absorption spectrum (Fig. 5) of the light-yellow silver colloids which is prepared by hot chemical reduction method after 5 minutes from boiling point, this Figure shows the surface Plasmon absorption band with a maximum of 425 nm which assign to existence of Ag nanoparticles [10]
Summary
In the last decades a large number of articles have been studied the Nano metric systems. The Surface plasmon absorption (SPA) lies in the visible part of electromagnetic spectrum for silver particles with a size from 1 - 100 nm and it is what confers the characteristic bright yellow to Ag NPs colloidal solutions [3].
