Ιnvestigations using vibrational spectroscopy/microscopy (Raman and infrared) AFM/Raman correlative microscopy

Dr. Dimitrios Palles

Group leader
Dr. Dimitrios PallesResearch Scientist A'

Using vibrational spectroscopy as the main tool, Dr. Palles’ contributions involve a variety of research topics ranging from basic to application-oriented research.

Through their distinct light-matter interactions, Raman (inelastic photon scattering) and infrared (resonance photon absorption) spectroscopies are complementary techniques sensitive in probing vibrational excitations in a material (gas, liquid, crystalline or amorphous solid). These excitations have energies of a few hundred meV (except NIR spectroscopy, which probes excitations in the range 500-1500 meV) and correspond to atomic motions. The motions can be either collective or more localized depending on the crystallinity of the material (higher crystallinity or longer range-order favoring a collective atomic motion) and are related to the way the various atomic species are geometrically arranged and vibrate with respect to each other so as to form part of the structure of the material. This is why vibrational spectroscopies are a very useful tool offering structural information of materials at the molecular level non-destructively (albeit indirectly).

The focus of this work over the years is to determine or clarify symmetry (e.g. regular vs distorted molecular group polyhedron) or geometry (e.g. tetrahedral vs octahedral arrangement) variations of materials structural entities at the micro/meso/nano-scale and arrive at correlations with some of their properties. These inhomogeneities are related to either structural variants of the same chemical composition (isomeric groups) or to the coexistence of different chemical phases or both. As vibrational spectroscopies are an indirect probe of the structure, an effort is made to correlate the in-house vibrational spectroscopies with other techniques such as XRD, NMR, AFM, etc., through either collaborations or literature search.

Starting from the collaboration with other TPCI researchers with expertise in vibrational spectroscopy back in 2007 (especially in glassy materials), a diverse network of collaborators has developed over the years and activity has expanded to areas ranging from applications in cultural heritage to hybrid perovskite materials to mineralogy, to name some examples. Part of this work is to provide research support in vibrational spectroscopy to other TPCI researchers, as well as in projects where TPCI is a service point of a national infrastructure (see e.g. Innovation-EL project). On several occasions, Dr. Palles acts as the liaison person between TPCI and external collaborators, in charge of initiating or performing vibrational spectroscopy measurements.

This activity will extend to include measurements at FTIR facilities using a synchrotron radiation source, i.e. with capabilities exceeding those found in a typical laboratory. Access to these facilities is granted through successful competitive applications for experiments. A feasibility study with Optical Photo-Thermal Infrared spectroscopy (O-PTIR) on fossilized bones/teeth has been performed in early 2025 at the Solaris synchrotron in Krakow, Poland.

Correlative microscopy is another area where Dr. Palles plans to dedicate part of his time: the acquisition and installation of a new AFM/Raman integrated setup, in the framework of an NHRF Centre of Excellence project, is expected to be completed in 2026.

Research Highlights

Science and technology/engineering applications

This output is the result of collaboration with other TPCI researchers or external academic partners. So far, these contributions include the study of

  1. oxide glasses: structure-bonding/property correlations, thermal-electric-field poling and second harmonic generation,
  2. hybrid perovskite materials,
  3. selected themes in mineralogy and/or wastewater management,
  4. surface-enhanced Raman scattering, etc.
Raman Study of the Slobodka Ordinary Chondrite (M. Simopoulou et al., J. Raman Spectrosc. 2025, DOI: 10.1002/jrs.6833). This figure shows an example of the identification of albitic jadeite using two techniques: Electron probe micro-analyzer (EPMA) and Raman spectroscopy.

(A) BSE image with selected position of analyzed albitic jadeite at the rim of a composite clast within the melt vein. (B) Locations of acquired Raman spectrum (white circle; #1) and EPMA analyses (black circles; #1 and #2). (C) Raman spectrum indicative of albitic jadeite (red line) from Slobodka section NHMW-L4372 compared to reference spectra from RRUFF database for jadeite (black line; RRUFF R050220.3) and for omphacite (gray line; RRUFF R061129). The Raman spectrum of albitic jadeite was obtained using a 632.8 nm excitation wavelength.

Archaeological materials / Heritage science

Based on the expertise acquired from (a) the study of the short- and medium-range order of oxide glasses, (b) applications in mineralogy and (c) vibrational spectroscopy in general, activity extended to the study of archaeological glass and other archaeological materials. Involvement in this area is a result of the strategic choice to contribute to an applied field like archaeometry, conservation science or more generally the study of cultural heritage related materials. Collaboration ranges from researchers within NHRF (either TPCI or the Institute of Historical Research) to external partners.
