A rapid test method for evaluating the delamination in glass packaging is provided. The method includes exposing the glass packaging means to an atmosphere consisting of steam in order to form a corrosion zone; and subsequently carrying out at least one other step. The other step includes: visualizing the corrosion zone using a light microscope; visualizing the corrosion zone by a staining process with a subsequent inspection process; or removing glass components in ultrapure water and quantifying the removed glass components. The rapid test method provides a conclusion about whether a glass packaging exhibits a tendency to delaminate or not in a simple and reliable manner and in a relatively short time span.

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 &#x3bb;when it is exposed to excitation light of an excitation wavelength &#x3bb;. 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 &#x3bb;, which is formed during exposure to the excitation light.
