Physics mechanism of laser-induced thermal evaporation. (a) Red shift of Raman peaks revealing temperature enhancement. (b) Raman spectra under different laser powers. Upper inset: Proportional relation between temperature and laser power. Lower inset: Relation between estimated temperature and Raman shifts. (c) Evaporation rate at different temperatures, revealed by temperature-dependent weight-losing investigation. The black, red and blue curves are the DTA, TG and DTG curves, respectively. The temperature in (b) is also color-mapped onto the thermal gravimetric curves.
