WebNov 12, 2024 · Due to the optothermal interaction, the colloids are directionally pulled towards the excitation point of the nanowire. Having reached this point, they are spatio-temporally trapped around the excitation location. By increasing the concentration of colloids in the system, we observe multi-particle assembly around the nanowire. ... WebOptothermal Raman (OTR) is a steady-state measurement technique, which directly determines thermal conductivity of a film. In this technique the Raman excitation laser acts as a heater to induce local heating in the film and micro Raman spectrometer is used as thermometer to determine this local temperature rise.
WebMay 13, 2024 · As a powerful, in situ and non-contact method, optothermal Raman technique has been developed to investigate the thermal conductivity in micro/nanoscale … WebA comparison in performances of our proposed Mach-Zehnder interferometer with other sensing schemes based on the laser-induced optothermal effect of magnetic fluids is …
