“…Usually, the target that is utilized in PLAL method to obtain different nanostructures could be made from various materials such as pure metals (i.e., Ag, Au, Pt, Pd and Cu), metal alloys (i.e., AgAu, PtPd, FePt, AuFe, AgFe, PtCu and PtAu), carbon-based targets (graphite and graphene oxide), oxides (GaO and SiO), selenides (ZnSe and CdSe), nitrides (GaN and TiN), sulfides (PbS and CdS), tellurides (CdTe), antimonides (InSb), and pressed targets (Cu/Zn and WO 3 /GO) [63,[77][78][79][80][81][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96].…”

Pulsed laser ablation in liquids (PLAL) is a physical method that is applied for the fabrication of noble metal nanostructures with different optical and morphological properties. The physical mechanism of laser ablation in liquid environment, the subsequent growth of nanostructures, the essential laser technological parameters that determine the nanostructures’ properties, and the liquid medium’s influence are discussed. The main advantages and disadvantages of the PLAL method are noted. Post-ablation treatment at optimal laser wavelength, fluence and duration of exposure has been indicated as a means of mitigating and overcoming the latter. The aging effect of the colloids and some applications of them are also marked. The most commonly used methods for studying the nanostructures’ characteristics such as UV/vis spectroscopy, high-resolution scanning transmission electron microscopy (HR-STEM), mass spectrometry (MS) and X-ray diffraction (XRD) are commented.

“…This has been amply demonstrated in a variety of experiments including optical limiting, Mie scattering, optical spatial soliton propagation, , and nonlinear optical absorption and refraction . In addition to chemical synthesis methods, laser ablation also provides a new method to prepare nanoparticle colloidal solutions. − With the help of new technologies, different kinds of nanoparticle colloidal solutions were prepared for research in the field of nonlinear optics. Two factors may affect the nonlinear optical characteristics of the colloidal solutions: first, the properties of the material from which the nanoparticles are made; second, the influences of Mie scattering, thermal lens effects, optical forces, and other factors in solutions. − It is possible to achieve large enhancements of nonlinear optical parameters by changing the size and shape of the nanoparticles .…”

In this paper, the nonlinear optical properties of magnetic nanoparticle colloidal solutions were studied by the Z-scan technique using 25 ps laser pulses at a wavelength of 1064 nm. Our results reveal that the formed magnetic nanoparticle clusters under high incident laser intensity will greatly affect the nonlinear optical characteristics of the solution. As the intensity of the pulsed laser decreases, the reverse saturable absorption coefficient and nonlinear refractive index of the sample tend to increase. The evolution of this nonlinear characteristic only occurs in liquid suspension. This is confirmed by fixing particles on a substrate upon which the responses observed in the liquid medium are no longer present. Besides, the possibility of generating optical trapping in the focus of the laser pulses is proposed to explain our experimental results.

In the present research work, Mg-doped zinc oxide Zn 0.1-x Mg x O (For x = 0.000, 0.002, 0.006, 0.010) nanoparticles were synthesized by co-precipitation method. The effect of Mg 2? ions substitution on structural, phase transformation, morphological, and optical properties was investigated using X-ray diffraction (XRD), Raman spectroscopy, Field emission scanning electron microscopy (FE-SEM), and UV-Visible spectroscopy (UV-Vis), respectively. The XRD study shows the formation of pure hexagonal wurtzite phase which was also confirmed using Rietveld refinement performed using Fullprof software. The average crystallite size of Mg-doped zinc oxide nanoparticles calculated using Debye-Scherrer relation found to vary from 43.36 to 36.12 nm with increase in Mg concentration from 0 to 10%. The UV-Vis study reveals the blue shift in optical band gap for all the samples as molar concentration of Mg increases in ZnO lattice which was attributed to quantum confinement effect. Further, results of other studies including XRD viz., Raman, UV-Vis, and FE-SEM show that this method of synthesis can be utilized for increasing the optical band gap of the Zn 0.1-x Mg x O nanocrystals by retaining the pure ZnO phase up to 10% doping of Mg 2? ions concentration.
