Advances in atomic physics

“…Advances in the LIBS measurements at our laboratory of lasers and new materials in the physics department at the faculty of science – Cairo University were achieved by studying the X-ray/particle emission from plasmas produced by laser irradiating nano-srtuctured targets, Hegazy et al [128] . In this experiment, nano-copper structures evaporated onto copper bulk disks and nano-gold structures evaporated onto gold ones were used.…”

Medical and Nanotechnology Applications of Lasers

“…Comparison of both studies in the case of nano-structured targets and bulk targets were performed at different laser fluencies (1 × 10 9 -1 × 10 12 W/cm 2 ) on the target. A 20% increase of the X-ray emission for nano-gold with respect to bulk gold was observed, however, the X-ray emission in the nano-copper and bulk copper was the same [166]. The researchers of the group also performed a comparative study of plasmas produced from nano and bulk ZnO targets.…”
