TL;DR: The irradiation of gold nanorod colloids with a femtosecond laser can be tuned to induce controlled nan orod reshaping, yielding colloid clusters with exceptionally narrow localized surface plasmon resonance bands.

TL;DR: Thorough optical and electron microscopy characterization indicates that plasmonic oligomers can be selectively trapped and welded, which has been analyzed in terms of a model that predicts with reasonable accuracy the relative concentrations of the main plAsmonic species.

TL;DR: This work has analysed the total quenching efficiency, as well as the actual values corresponding to the RET process between UCNPs and GO sheets with three different chemical compositions, and indicates that excitation and emission absorption by GO sheets are the major contributor to the observed luminescence quench in these systems.

TL;DR: In this paper, femtosecond laser ablation was used to generate highly concentrated silver colloidal nanoparticle solutions, but these high concentrations usually lead to agglomeration of the nanoparticles, rendering the solution nearly useless.

TL;DR: In this paper, exposed and embedded silver nanoparticles were grown on Si(100) and silica substrates by laser ablating high-purity silver and SiO2 targets in vacuum using a femtosecond Ti:sapphire laser delivering 45 fs pulses at 804 nm and 1 kHz repetition rate.
