Analysis of products from breakdown of liquid benzene, toluene and cyclohexane caused by Nd3+:YAG pulsed laser irradiation

Analysis of Titanium Nanoparticles Created by Laser Irradiation under Liquid Environments

“…28 Diamond-like carbon and other carbon solids also have been created without the use of a graphite rod by irradiation with a tightly focused laser into carbon-rich solutions. 29,30 The following body of work is focused on the creation and characterization of titanium-based nanoparticles and the experimental parameters that govern their properties.…”

Graphite-Shelled Si Nanoparticles and Their Au/Si Heterodimers: Preparation, Photoluminescence, and Second Harmonic Generation

“…The short processing time of laser treatment on the solid target efficiently elevated the local temperature to facilitate the separation of carbon from SiC substrate for the growth of the onion-like carbon. Organic solvents, such as toluene, utilized in our studies served not only as a cooling role but also as a carbon source . Perhaps the aromatic debris, containing hexagonal carbon rings from toluene, has facilitated the graphitization process to build up graphitic carbon layers from the metastable silicon carbides in the course of laser ablation.…”

“…The QYs were calculated relative to the standard Coumarin 460 in ethanol. It is known that a near-infrared pulsed laser can break down organic liquids, resulting in various carbon fragments such as C 1 , C 2 , and other CH-based products . The as-prepared Si nanocrystals might have been composed of some carbon matrix.…”

“…It is known that a near-infrared pulsed laser can break down organic liquids, resulting in various carbon fragments such as C 1 , C 2 , and other CH-based products. 16 The as-prepared Si nanocrystals might have been composed of some carbon matrix. Under similar high-temperature circumstances using arc discharge preparation in organic liquid, 17 the onion-like nanocarbons, consisting of concentric graphitic shells, were grown by the pyrolysis of benzene liquid.…”

“…Organic solvents, such as toluene, utilized in our studies served not only as a cooling role but also as a carbon source. 16 Perhaps the aromatic debris, containing hexagonal carbon rings from toluene, has facilitated the graphitization process to build up graphitic carbon layers from the metastable silicon carbides in the course of laser ablation. The preparation presented here may provide an approach to prepare graphite-shelled QDs by laser ablation of semiconductor targets using an appropriate organic solvent containg aromatic group.…”
