Rhombohedral calcite group exhibiting organic fluorescence

Rhombohedral calcite group, Beez, Namur, Belgium. It exhibits the typical yellow-green fluorescence and afterglow (PeL image). At shorter excitation wavelengths, the colour becomes more greenish due to a shift in emission maximum. Black full: 365 nm excitation. Blach dashed: 275 nm excitation.
