Peng et al. [150] prepared AgAu nanoalloys via three different procedures by using laser-induced heating (i) mixture of Au nanoparticles and Ag(I) ions irradiated by a 532 nm laser, (ii) mixture of Au and Ag nanoparticles irradiated by a 532 nm laser, and (iii) mixture of Au and Ag nanoparticles irradiated by a 355 nm laser. In procedures (ii), nanoalloys with a sintered structure were obtained. The morphology of the obtained nanoalloys depended not only on the laser wavelength but also on the concentration of nanoparticles in the initial mixture. Large-scale interlinked networks were observed upon laser irradiation when the total concentration of Ag and Au nanoparticles in the mixture increased.

Using the same apparatus, the mobility of very small particles at the sooting limit of a premixed flame has been estimated 53). The observed ionization signals were attributed to laser-induced heating and subsequent thermal ionization of the soot particles. An approximate estimate of the particle size was made from the mobility measurements.

In hybrid cutting operations, the conventional cutting process is simultaneously supported by another form of energy, in particular by thermal energy (laser-induced heating of the workpiece) or kinetic energy (sonotrode-induced movement of the cutting tool).

A multifunctional nanoplatform is proposed in Ref. [87], where simultaneous laser-induced heat generation by gold nanoparticles and temperature sensing by (Gd, Yb, Er)203 nanorods are operative. The local temperature is also obtained from the Boltzmann distribution of the Er " upconversion intensities ratio, but in the extended range from 300 to 1050 K, or Planck s law for white light emission in the range from 1200 to 2000 K.
