Laser-Induced Breakdown Spectroscopy 2D Distribution Mapping of Nanoparticles

Popis výsledku v původním jazyce

The technique described in this presentation allows detection of metal nanoparticles and quantum dots (QDs) injected on the silica gel spread on aluminum foil or filtration paper. The modified laser system UP-266 MACRO equipped with software controlled stages in x and y directions was used. The prepared substrates with injected nanoparticles were placed into a lab-made holder. Pulse energy was set to 10 mJ while plasma emission was collected and transported by means of a 3 m long optical fiber into the entrance of a monochromator (Jobin Yvon, TRIAX 320) and detected with the ICCD detector (Princeton, PI MAX 3). The raster covered 15 × 15 points with spacing 500 um while laser spot diameter was approximately 100 um. In double pulse configuration (DP LIBS) the second, re-heating laser system, that propagates beam parallel to the sample surface was used Q-Smart Nd:YAG laser at fundamental wavelength 1064 nm and energy 100 mJ per pulse.
