“…1 In particular, pulsed laser ablation of solids in liquid environments (PLAL) has been extensively investigated as a technique for the fabrication of nanoparticles (NPs) of a large variety of materials including metals, alloys, ceramics, and semiconductors. [2][3][4][5][6][7][8][9][10][11][12][13] Remarkable advantages of this method over chemical synthesis rely on the simplicity of the procedure, the weak agglomeration effects, and the lack of impurities caused by chemical precursors. The pioneering work on PLAL for materials processing on the stabilizing agent.…”

Aqueous suspensions of platinum colloidal nanoparticles of varying size and polydispersity have been produced by ablation of a platinum target with a nanosecond Q-switched Nd:YAG laser. Several laser wavelengths (1064, 532 and 266 nm) and stabilizing agents (citrate and polymers PEG, PVA and PVP) were employed. Laser ablation with the infrared and visible wavelengths leads to spherical amorphous nanoparticles with a bimodal distribution of diameters, featuring a global maximum in the range 5-10 nm and a shoulder extending to 25 nm. Such bimodal distributions plausibly arise from thermal and explosive vaporization mechanisms occurring in different time scales, as proposed in earlier studies.Ultraviolet ablation of Pt at 266 nm, reported here for the first time, produces crystalline nanoparticles of small size (1-4 nm diameter), with a weak onset of larger particles (6-8 nm). The ablation at 266 nm also produced an appreciable yield of large rod-like particles of size ∼ 10 x 70 nm 2 , especially in the presence of PEG and PVA. The Pt nanoparticles served to fabricate films capable of assisting the laser desorption ionization (LDI) of a model peptide. The best analytical performance for LDI mass spectrometric detection was obtained with Pt nanoparticles surface functionalized with citrate and PVA.

“…The whole process can take place in either liquid environment or a vacuum chamber, known as Liquid-phase Pulsed Laser Ablation (LP-PLA or PLA) and Pulsed Laser Deposition (PLD), respectively. Pulsed laser ablation method, which has been proven to be an effective method for fabrication of nano-sized metal QDs, including Au, Ag, Ti and Ni [90,[95][96][97], is also a promising method to fabricate QDs of compound semiconductors, such as FeO, ZnO, CdS and TiO 2 [55,91,92,98]. Ajimsha et al [55] prepared ZnO QDs with an average size of 7nm in various liquid media using PLA method ( Figure 5).…”

“…Nanoparticles are grown in this fast heating and quenching process. In this liquid-phase laser ablation, fabrication of nanoparticles of metal such as Ag and Ti was reported [1][2][3][4]. Metal oxide or oxide semiconductors such as ZnO, SnO 2 , TiO 2 , and Mn 3 O 4 were also synthesized [5][6][7][8][9][10][11].…”

Red luminescence of Eu3+ doped ZnO nanoparticles fabricated by laser ablation in aqueous solution

Fabrication of Eu 3+ -doped ZnO nanoparticles by laser ablation in liquid medium is reported. Sintered disks made of mixed powders of ZnO and Eu 2 O 3 are used for targets, and surfactant of sodium dodecyl sulfate or LiOH is included in solution. Round-shaped nanoparticles with the diameter of 5∼30 nm are synthesized. When the ZnO host is photoexcited, broad green photoluminescence (PL) of oxygen vacancies in the ZnO host as well as red PL of Eu 3+ is observed at room temperature. The red PL peak of Eu 3+ included in the ZnO host lattice is different from that of the source material of Eu 2 O 3 . Energy transfer from the ZnO host to Eu 3+ is demonstrated in site-selectively excited PL spectra and its excitation spectra. This result shows that the liquid-phase laser ablation is useful for doping active centers into nanoparticles.
