Facile Synthesis and Characterization of Highly Luminescent Bi2WO6 Nanoparticles for Photonic Application

Facile manufacturing of highly luminescence materials is in demand right now for a wide range of photonic applications. In this work, bismuth tungstate nanoparticles (Bi2WO6 NPs) were synthesized using a simple co-precipitation process at room temperature without using any hazardous solvents. The optical and structural properties of the prepared nanopowders were investigated using various techniques, and the photoluminescence measurement was performed using different excitation wavelengths. Bi2WO6 NPs were embedded in a flexible matrix, and their photoluminescence property was studied. X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) investigations confirmed the successful synthesis of the related chemical binding in the synthesized nanostructure. According to the FESEM image, cubic-like and spherical-like particles were observed in the average diameter size of 0.9 μm. Some aggregates were detected in the prepared Bi2WO6 nanopowder, attributed to the larger Bi2WO6 particles. Intense luminescence colors of violet, blue, yellow, and red under ultraviolet excitation were obtained which could be a suitable candidate for photonic application.
