Bi-metallic Pd/Au nanoparticles prepared by UV-excimer laser exposure

Porous spherical gold nanoparticles via a laser induced process

“…The sample position is achieved using an XY-translational stage. 24,28 Selective chemical etching For the etching process of the mixed Ag/Au particles, a solution of 65% HNO 3 + H 2 O with a volume ratio of 1 : 2 (e.g. 5 ml 65% HNO 3 + 10 ml H 2 O) was used.…”

“…These extensive relationships have been demonstrated in various literature studies and previous publications for different material systems. [23][24][25][26][27][28] A material mixture in particles based on a multilayer system deposited on a substrate is very well realizable with this method, since excimer laser irradiation is characterized by fast heating, up to melting or evaporation in the ns range. The fast cooling rate can suppress phase separation during solidication.…”

Formation of nanoflowers: Au and Ni silicide cores surrounded by SiOx branches

“…The research of thin film dewetting has been extended to bilayers and multilayers for the synthesis of multicomponent nanoparticles [8][9][10][11][12][13][14][15][16], like alloyed AuNi and AuAg nanoparticles produced by the solid-state dewetting of bilayers [17][18][19][20][21][22][23][24][25]. Apart from Au, both Ni and Ag can also catalyze the growth of NWs based on the VLS mechanism [26][27][28], and Si NWs have been grown using alloyed AuAg nanoparticles [29].…”

Impact of thermal annealing and laser treatment on the morphology and optical responses of mono- and bi-metallic plasmonic honeycomb lattice

“…48 Short laser pulses are used to rapidly heat or melt, or even vaporize and ionize the materials. [49][50][51][52] Such fast and localized deposition of energy can result in local plasma generation. Followed by a fastcooling process, this method produces plasmonic nanoparticles without thermal equilibrium.…”
