- Abstract
- The prototype of a portable instrument, based on the time-correlated
single-photon counting method, purposely assembled for in situ
measurements of luminescence lifetimes on artwork surfaces, is here
presented. Preliminary tests have been carried out using the portable
instrument and the results have been compared with those obtained using
a bench instrument. In this way we have proven that the prototype
provides lifetime measurements with good precision. It is also shown
that fluorescence lifetime determinations, coupled with steady-state
fluorescence spectra, allow the distinguishing, on laboratory samples,
of different red organic lakes having similar fluorescence spectra,
achieving new boundaries in the nondestructive diagnosis of artwork
materials. The first in situ application of the technique on an
original work of art, The Book of Kells, held at Trinity College
Library, Dublin, highlighted the diagnostic potential of coupled
steady-state and time-resolved luminescence spectroscopy in the
identification of organic colorants. (literal)
