Vibrational spectroscopy, including infrared and Raman optical spectroscopy, is an instrumental technique for fingerprinting molecular structures and the chemical compositions of different materials.
Stanford researchers at the Dionne Lab have introduced new vibrational spectroscopy, termed electron- and light induced stimulated Raman (ELISR) scattering, in electron microscopy for simultaneous high-resolution chemical mapping of various samples.
Stanford researchers have designed a powerful plasmonic coaxial aperture as a low-power optical trap for nanosized specimens, a regime that is inaccessible with the other designs.
Stanford researchers have developed a novel tomographic technique, cathodoluminescence (CL) spectroscopic tomography, to probe optical properties in 3D with nanometer-scale spatial and spectral resolution.
