Abstract
A method and a system for determining material-, size-, and morphology-dependent photothermal properties of particles dispersed in solutions, the method comprising using coherently detected pulsed THz radiation, tracking a temperature-dependent refractive index change of the particles dispersion in time and space, and correlating the temperature-dependent refractive index change of the particles dispersion in time and space to temperature values. A system comprises a source of electromagnetic radiation; a THz emitter; a THz detector; and a vessel containing a dispersion of particles, wherein the source of electromagnetic radiation is configured to emit electromagnetic radiation to excite the particles in the dispersion; the THz emitter is configured to send THz radiation to the vessel and the THz detector is configured to receives THz radiation returned by from the vessel.
