The increasing use of supercritical fluids in a wide range of practical applications has motivated us to understand the fundamental aspects of these fluids. In this article, supercritical fluid structures, probed by three spectroscopic methods, i.e. dynamic light scattering, terahertz absorption, and vibrational Raman spectroscopies, are reported. As another topic, nanomaterials, synthesized by pulsed-laser ablation of solid materials in a supercritical fluid, are described. Furthermore, applications of the synthesized nanomaterials to optoelectrical devices are briefly summarized, i.e., a Si quantum dot LED and solar cell materials.
