UV-Vis absorption spectra of materials A, B and A3, B3 in a range 900–250 nm (A). Change of medium temperature caused by material A3 (B) and B3 (C) at different concentrations vs material A (100 µg/mL) under NIR light irradiation 2 W/cm2; photostability of materials A3 and B3 (100 µg/mL) under on/off cycles of NIR laser (D).
