Abstract

BaWO4 nanorods have been successfully synthesized in w/o microemulsion system containing barium ions via a simple reaction between Ba2+ and . The BaWO4 Nanorods were characterized by XRD, TEM, and SEM, respectively. Results showed that the solvents composition—volume ratio of 4-dioxane and distilled water—played the key role in the formation of BaWO4 Nanorods. Furthermore, the strong vibration at 925 cm﹣1 on its Raman spectrum indicated that the BaWO4 nanorods is good at stimulating Raman scattering in transient and steady-state, making it as a promising candidate material for laser with self-raman conversion of radiation inside the active medium.

Highlights

Nowadays, tungstate materials, BaSO4, have attracted much attention in view of its luminescent behavior and structural properties [1] [2]
The obtained BaWO4 particle in water-in-oil (W/O) microemulsion system was characterized by X-ray diffraction (XRD), and the typical XRD pattern was shown in Figure 1, in which all the peaks could be indexed to the pure BaWO4 particle with a tetragonal unit cell (a = b = 0.5626 nm, c = 1.2744 nm)
It is well known that different concentrations of surfactants can form micelles with varied morphologies [15], which could be utilized for the modification of crystal growth

Summary

Introduction

Tungstate materials, BaSO4, have attracted much attention in view of its luminescent behavior and structural properties [1] [2]. The material is not hydroscopic and transparent in visible and near-infrared spectral range. It is a promising material for crystalline nano- and picoseconds Raman lasers. It is well known that different surfactants can form micelles with variable morphologies. This can be utilized for the modification of crystal growth [10] [11] [12]. The different morphologies and sizes of BaWO4 crystals could be synthesized by the employment of super-molecule templates composed of biomembrane and organic reagents at room temperature [13].
