Nanoparticles with quantum dots for restoring
monuments

11th May 2020by admin0

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.

    New Fusion

    The New Fusion technology is based on a phenomenon called triplet-triplet annihilation (TTA) which is a process in which two triplet excitons annihilate and produce a higher energy singlet exciton.
