Abstract

We synthesized ZnSe nanoparticles through pulsed laser ablation in liquid (PLAL). Laser ablation was performed using a Nd:YAG laser with a wavelength of 1064 nm, a pulse energy of 135 mJ, and a pulse duration of 10 ns. X-ray diffraction analysis confirmed the formation of hexagonal ZnSe nanocrystals with an average crystallite size of 27.53 nm. Scanning electron microscopy, atomic force microscopy, and energy-dispersive X-ray spectroscopy characterized the particle size, morphology, and stoichiometry of the nanoparticles. Absorption and photoluminescence spectra revealed a bandgap of 3.10 eV and demonstrated excitonic emission in the nanoparticles under excitation by the second harmonic of the laser.
