Narrowband vs Broadband Optical Absorption: Photothermal Behavior of Laser-Synthesized TMDC Nanoparticles / A.Ushkov, N.Belozerova, [a.o.]. – Text : electronic // Applied Surface Science. – 2026. – Vol. 730. – P. 166095. – URL: https://doi.org/10.1016/j.apsusc.2026.166095. – Bibliogr.: 41.
Ultrapure Transition Metal Dichalcogenides (TMDC) colloids were synthesized by femtosecond pulsed laser ablation in deionized water, a single-step method that yields ligand-free suspensions stabilized by the native surface charge, avoiding surfactants or complex chemistries. We perform a comparative analysis of prepared WSe&sub(2) and PdSe&sub(2) nanoparticles, revealing a profound divergence in their photothermal properties in NIR-I transparency window. Crystalline WSe&sub(2) produces a wavelength-selective, resonant heating in NIR-I, whereas PdSe&sub(2) displays almost wavelength-independent photothermal conversion. By separating several size fractions from the same synthesis route we have explicitly quantified size-dependent photothermal behavior in colloids and compared it with theory. For PdSe&sub(2) nanoparticles (NPs) we report the highest experimental photothermal conversion efficiency 81% at 700 nm, whereas WSe&sub(2) NPs possess the highest efficiency of 71% at 770 nm due to the excitonic resonance. Together with material-independent photothermal maps derived from the Mie theory, our findings establish a clear framework that links the bulk optical response and colloidal size distribution to the wavelength-resolved heating in NIR-I. The ability to deterministically synthesize high-purity colloids with either narrowband or broadband absorption via a single-step process opens avenues for applications requiring precise spectral control of light-to-heat conversion
