Special Issue Information

Dear Colleagues,

Nowadays, laser-based synthesis of nanoscopic objects and nano-structures has found its place in many areas, such as plasmonic sensors, solar cells, catalysis, nano-bio-photonics, the automobile industry, medicine, etc. Modern progress in these applications is based on a combination of both experimental and numerical studies focused not only on the fabrication, but also on the optical, magnetic and photo-thermal properties of the obtained nano-objects.

This Special Issue of Nanomaterials aims to collect papers covering all types of measurements and calculations related to the exciting properties of laser-synthesized nano-objects. The involved nano-objects can include metallic and hydride nanoparticles, core-shells, Janus particles, fractal aggregates, as well as colloids and/or nano-composites. The articles should not only describe laser-based fabrication techniques, but, importantly, should bring more light on the resulting unique optical, magnetic, magneto-optical, thermal and/or photo-thermal properties with a strong application potential.

Laser-Ablative Synthesis of Isotope-Enriched Samarium Oxide Nanoparticles for Nuclear Nanomedicine

Nuclear nanomedicine is an emerging field, which utilizes nanoformulations of nuclear agents to increase their local concentration at targeted sites for a more effective nuclear therapy at a considerably reduced radiation dosage. This field needs the development of methods for controlled fabrication of nuclear agents carrying nanoparticles with low polydispersity and with high colloidal stability in aqueous dispersions. In this paper, we apply methods of femtosecond (fs) laser ablation in deionized water to fabricate stable aqueous dispersion of 152Sm-enriched samarium oxide nanoparticles (NPs), which can capture neutrons to become 153Sm beta-emitters for nuclear therapy. We show that direct ablation of a 152Sm-enriched samarium oxide target leads to widely size- and shape-dispersed populations of NPs with low colloidal stability. However, by applying a second fs laser fragmentation step to the dispersion of initially formed colloids, we achieve full homogenization of NPs size characteristics, while keeping the same composition. We also demonstrate the possibility for wide-range tuning of the mean size of Sm-based NPs by varying laser energy during the ablation or fragmentation step. The final product presents dispersed solutions of samarium oxide NPs with relatively narrow size distribution, having spherical shape, a controlled mean size between 7 and 70 nm and high colloidal stability. The formed NPs can also be of importance for catalytic and biomedical applications. Full article

A series of five excited-state intramolecular proton transfer (ESIPT) emitters based on a 2-(2′-hydroxyphenyl) benzoxazole (HBO) scaffold, functionalized with a mono-or bis-(trialkylsilyl) acetylene extended spacer are presented. Investigation of their photophysical properties in solution and in the solid-state in different matrix, along with ab initio calculations gave useful insights into their optical behavior. Random lasing studies were conducted on a series of PMMA doped thin films, showing the presence of stimulated emission above the threshold of pumping energy density (ρth ≈ 0.5–2.6 mJ cm−2). In this work, the similarity of four level laser systems is discussed in light of the ESIPT photocycle. Full article
