Carbon quantum dots synthesis by laser ablation of graphene oxide in biocompatible solutions

A biocompatible dispersion of carbon quantum dots (CQDs) has been obtained by laser irradiation of graphene oxide (GO) in liquid media. The CQD synthesis uses a pulsed IR laser operating at 970 nm, with a 100 ms pulse duration and a fluence of 1.1 kJ/cm2. The carbon target consis...

Backward Plasma Acceleration of Aluminum, Copper, Silver, and Tantalum Ions From 10 10 up to 10 15 W/cm 2 Pulse Laser Intensity

ABSTRACT Measurements of ion acceleration in laser‐generated plasma obtained at intensities from 10 10 up to 10 15 W/cm 2 using IR laser ablation of aluminum, copper, silver, and tantalum in high vacuum are presented. At low intensity, data were acquired from the MIFT Department...
