Abstract

In this research displays, photophysical properties Prodigiosin dye product from Serratia marcescens through absorption and fluorescence spectra of this pigment. The absorption spectra of prodigiosin were studied and the highest absorption peak in the spectrum at a wavelength (537nm). The spectra of fluorescence of Prodigiosin molecules have been measured appear band at a wavelength (557 nm).
This metabolite mixing with Curcumin dyes dissolved in methanol at concentrations [10µM], [1µM] to achieve energy transfer respectively. The values of the Förster radii R0 were calculated from molar absorptivity of concentration [10µM] from spectral overlap by used the MatLab program, the quantity R0 for Förster resonance energy transfer (FRET) between given donor and acceptor molecules found amount 4.9834 ºA.Via mix produced complex molecules, excited by a wavelength (430 nm). This leads to charge transfer between molecules consequently the stability of the group, by energy nonradiative. Found values the quenching factor (Q) and it found it depends on the value of concentration. Thus, the data obtained is useful enough to be relied upon as a database of spectra for Prodigiosin dye.
