Pulsed Laser Ablation of Graphite Target in Dimethyformamide

Influence of the per pulse laser fluence on the optical properties of carbon nanoparticles synthesized by laser ablation of solids in liquids

“…From these results, it is clear that the PL emission can be tuned from blue to yellow color. This effect has been previously reported for CNPs obtained using the same technique by Thongpool et al and Li et al [24,25,29]. Tunability of color emission of carbon nanostructures is not a new result; it has been also reported in those carbon-based nanomaterials produced through chemical methods [30].…”

“…Some other structures like carbon nitride nanocrystals in liquid ammonia [21] and onion-like carbon-encapsuled cobalt carbide core/shell nanoparticles in acetone [22] have also been obtained using nanosecond laser pulses. The LASL technique has been likewise reported to be an efficient technique to produce graphene in liquid nitrogen [23] or for the obtaining of dispersed in ethanol carbon nanoparticles with blue-green PL emission [24] or dimethyformamide [25]. Carbon dot-like nanoparticles suspended in deionized water have been also obtained through this technique using an UV laser for its production.…”

Preparation and characterization of copper oxide nanoparticles decorated carbon nanoparticles using laser ablation in liquid

“…PLAL can use to prepare an extensive variety of novel substances and the final products are typically inside the shape of nanoparticles that stay suspended within the liquid medium, and can be separated by filtration and evaporation of the liquid [12]. In addition, this method is simple and does not require a vacuum system [13]. In this work, carbon nanoparticles decorated with different copper oxide nanoparticles ratio were prepared using PLAL and characterization of these nanoparticles were studied by several techniques.…”

Laser processing of graphene and related materials for energy storage: State of the art and future prospects

“…Ablation processes can also be conducted in liquid media for obtaining graphene-based materials. Bilayer and few-layer graphene nanowalls and carbon NPs have been achieved by laser ablation of graphite targets immersed in liquids such as water and dimethylformamide [194][195][196]. GQDs have also been synthesized by pulsed laser ablation of carbon nano-onions immersed in distilled water [197].…”
