Abstract

A method for the formation of a functional biopolymer matrix based on specific mixing of chitosan and gelatin is proposed. It makes it possible to obtain the binding complexes of organic dyes such as eosin (energy donor) and rhodamine C (acceptor) with chitosan that are advantageous for the realization of inductive-resonant electron excitation energy transfer between these dyes. An efficient sensitized steady-state fluorescence of rhodamine C and superluminescence of this dye under pulsed excitation were observed in this system. The obtained results can be used for the development of two-component solid-state dye lasers.
