Organic Semiconductor Lasers and Tailored Nanostructures for Raman Spectroscopy

The book explores the use of organic semiconductor distributed feedback lasers as a free-space excitation source in Raman spectroscopy, enhancing detection sensitivity through surface-enhanced Raman scattering (SERS). It details the creation of gold-coated polymeric nanopillar arrays to achieve SERS conditions. The application of organic-laser-excited SERS measurements is demonstrated by analyzing the concentration variations of the biomolecule adenosine in aqueous solutions, showcasing innovative techniques in spectroscopic analysis.
