Abstract

The invention discloses a standard for referencing luminescence signals, having an optically transparent base material comprising a lanthanum phosphate glass, a fluorophosphate glass, a fluor-crown glass, a lanthanum glass, a glass-ceramic formed therefrom or a lithium aluminosilicate glass-ceramic, the base material including a bulk doping with at least one constituent which is luminescent and comprises at least one rare earth and/or a nonferrous metal, in particular cobalt, chromium or manganese.
