This paper presents a study of the dependence of the size and optical characteristics, as well as the productivity of laser synthesis of zirconium nitride (ZrN) nanoparticles (NPs) on laser ablation parameters. It is shown that changing the distance between the focusing lens and the target surface allows one to control the mode and half-width of the size distribution from (59 ± 35 nm) to (29 ± 14 nm), as well as spectrally shift the plasmon resonance peak from 638 nm to 680 nm. Additionally, a possibility of controlling the size characteristics of ZrN NPs when changing the laser radiation energy is demonstrated. Increasing the laser pulse energy from 10 to 100 μJ makes it possible to vary the NP size from (27 ± 13 nm) to (47 ± 30 nm). The results form a quantitative basis for the production of laser-synthesized ZrN NPs with controlled size and optical properties for applications in biomedicine. [ABSTRACT FROM AUTHOR] |
