Engineered substrates sharpen single nanoparticle plasmon spectra
Sydney, Australia (SPX) Jan 30, 2026
A research team led by the Singapore University of Technology and Design has demonstrated that spectral broadening in single-nanoparticle plasmons is not an unavoidable consequence of metal losses but can be overcome by tailoring the photonic environment beneath the particle. Their approach, reported as a Letter in Physical Review B, achieves high-quality plasmonic hotspots in individual metal n
