Abstract

Pulsed laser ablation in a liquid phase was successfully employed to synthesize a barium molybdate (BaMoO₄) nanocolloidal suspension. The nanocolloidal suspension was composed of well-dispersed and horizontally assembled BaMoO₄ aggregates. The BaMoO₄ aggregates showed predominantly elliptically shaped nanorods with sizes between 100 and 200 nm. The preferential elliptical growth was rationalized from the viewpoint of the intrinsic structure of BaMoO₄. The optical properties of the prepared BaMoO₄ colloidal nanoparticles were investigated using Raman spectroscopy, UV-vis spectroscopy and photoluminescence (PL) spectrophotometry. The optical band gap was estimated by Tauc and Menth's law. The PL emission feature was decomposed into several individual Gaussian components, which could be interpreted by a Jahn-Teller splitting effect on the [MoO₄] ^2- tetrahedron of the BaMoO₄ colloidal nanoparticles.
