Abstract
This Letter presents the fabrication and characterization of a
perylene (Per) and Rhodamine 6 G (Rh 6 G) co-doped polymeric fiber. The
spectroscopic properties (luminescence spectra, attenuation, energy
transfer) of the co-doped polymethyl methacrylate (PMMA) fiber are
presented. Two different concentrations of Rh 6 G (2.2×10−4 and
4.1×10−4 mol/L) and a constant Per concentration
(6.2×10−4 mol/L) are used in the experiments. The
luminescence spectrum changes versus the fiber length are discussed.
Additionally, the ratio of the maximum fluorescence peaks of the used dyes
is calculated versus the fiber length. The obtained results show the
energy transfer from Per (donor) to Rh 6 G (acceptor). The proposed
co-doped fiber can be used in applications in lighting and sensor
technology.
