Abstract

The invention relates to an arrangement for fluorescence amplification including a substrate, a fluorescence amplifier coating applied to the substrate, and a thin fluorescencable material which lies on the coating and emits light with the emission wavelength λE when it is exposed to excitation light of an excitation wavelength λA. The fluorescence amplifier coating includes an interference layer system of high-index and low-index dielectric layers, which reflects at least the excitation light. What is crucial for the design of the coating is that the fluorescencable material applied to the coating is arranged on the surface of the coating in the region of the maximum of the electric field amplitude of the standing wave with the excitation wavelength λA, which is formed during exposure to the excitation light.
