The fluorescence emitted by zinc oxide quantum dots can be used to determine the penetration depth of certain substances used in the restoration of historical buildings. Researchers from Pablo de Olavide University (Spain) have tested this with samples collected from historical quarries in Cadiz, where the stone was used to build the city hall and cathedral of Seville.
