- Abstract
- After electronic excitation by ultraviolet or visible radiation, atoms
and molecules can undergo thermal or radiative deactivation processes
before relaxing to the ground state. They can emit photons with longer
wavelengths than the incoming exciting radiation, that is, they can
fluoresce in the UV-vis near-infrared (NIR) range. The study of
fluorescence relaxation processes is one of the experimental bases on
which modern theories of atomic and molecular structure are founded.
Over the past few decades, technological improvements in both optics
and electronics have greatly expanded fluorimetric applications,
particularly in analytical fields, because of the high sensitivity and
specificity afforded by the methods. Using fluorimetry in the study and
conservation of cultural heritage is a recent innovation.
In this Account, we briefly summarize the use of fluorescence-based
techniques in examining the constituent materials of a work of art in a
noninvasive manner. Many chemical components in artwork, especially
those of an organic nature, are fluorescent materials, which can be
reliably used for both diagnostic and conservative purposes. We begin
by examining fluorimetry in the laboratory setting, considering the
organic dyes and inorganic pigments that are commonly studied. For a
number of reasons, works of art often cannot be moved into
laboratories, so we continue with a discussion of portable instruments
and a variety of successful \"field aplications\" of fluorimetry to works
of cultural heritage. These examples include studies of mural
paintings, canvas paintings, tapestries, and parchments. We conclude by
examining recent advances in treating the data that are generated in
fluorescence studies. These new perspectives are focused on the
spectral shape and lifetime of the emitted radiation.
Recent developments have provided the opportunity to use various
spectroscopic techniques on an increasing number of objects, as well as
the ability to fully characterize very small amounts of sample, either
in a laboratory setting or on site. Thus, a new technological highway
is open to scientists; it is still difficult to navigate but offers an
enormous potential for investigating objects without touching them.
Fluorescence spectroscopy is one of the most important of these
techniques. (literal)
