Although oxide nanoparticles are ubiquitous in science and technology, a multitude of compositions, phases, structures, and doping levels exist, each one requiring a variety of conditions for their synthesis and modification. Besides, experimental procedures are frequently dominated by high temperatures or pressures and by chemical contaminants or waste. In recent years, laser synthesis of colloids emerged as a versatile approach to access a library of clean oxide nanoparticles relying on only four main strategies running at room temperature and ambient pressure: laser ablation in liquid, laser fragmentation in liquid, laser melting in liquid and laser defect‐engineering in liquid. Here, established laser‐based methodologies are reviewed through the presentation of a panorama of oxide nanoparticles which include pure oxidic phases, as well as unconventional structures like defective or doped oxides, non‐equilibrium compounds, metal‐oxide core–shells and other anisotropic morphologies. So far, these materials showed several useful properties that are discussed with special emphasis on catalytic, biomedical and optical application. Yet, given the endless number of mixed compounds accessible by the laser‐assisted methodologies, there is still a lot of room to expand the library of nano‐crystals and to refine the control over products as well as to improve the understanding of the whole process of nanoparticle formation. To that end, this review aims to identify the perspectives and unique opportunities of laser‐based synthesis and processing of colloids for future studies of oxide nanomaterial‐oriented sciences.

“…Zhang and his coworkers synthesized carbon/graphene QDots without any surfactant through alkaline assisted oxidation of cellulose acetate and studied their photoluminescence properties, they discovered that as the concentration of the colloid varies the luminescence properties can be changed 8 . Sadeghi and his coworkers studied the effect of changing the liquid environment on the properties of nanoparticles and graphene nanosheets by liquid ablation of graphite using pulsed Nd: YAG laser, they found that the liquid environments have a strong effect on the size and morphology of the nanostructures 9 , Dizajghorbani and his coworkers studied the effect of ablation time and laser fluence on the composition, morphology and optical properties of the synthesized nanoparticles from Cu target in water, they observed that there is an increase in the crystallinity of the phase of Cu2O as the laser fluency increases at a constant ablation time, 7 While Yogesh and coworkers have studied the photoluminescence properties of post ablated water soluble nanoparticles in ethanol, he discovered that the Carbon nanoparticles exhibit wavelengthdependency upon photoluminescence emission, 5 , and there are still researchers working in this field.…”

Pulsed liquid laser ablation is considered a green method for the synthesis of nanostructures because there are no byproducts formed after the ablation. In this paper, a fiber laser of wavelength 1.064 µm, peak power of 1 mJ, pulse duration of 120 ns, and repetition rate of 20 kHz, was used to produce carbon nanostructures including carbon nanospheres and carbon nanorods from the ablation of asphalt in ethanol at ablation speeds of (100, 75, 50, 10 mm/s). The morphology, composition and optical properties of the synthesized samples were studied experimentally using FESEM, HRTEM, EDS, and UV-vis spectrophotometer. Results showed that the band gap energy decreased with decreasing the ablation speed (increasing the ablation time), the minimum mean particle size of the synthesized samples was 76 nm at an ablation speed of 100mm/s, while the maximum mean particle size was 98 nm at ablation speed of 50 mm/s, the nanospheres were agglomerated to form larger spherical nanoshapes. All the synthesized carbon nano colloids exhibited a blue-green PL emission. It was concluded that the presence of carbon nanorods has an effect on the optical properties of the synthesized nanospheres.
