Synthesis and Spectroscopic Properties of Silver-Fluorescein Codoped Phosphotungstate Hollow Spheres

Abstract

A Silver-fluorescein codoped phosphotungstate hollow sphere has been successfully synthesized using chemical precipitation method by introducing silver ions and fluorescein at room temperature. This hybrid nanomaterial shows uniform structure, exhibiting a strong emission spectrum with peaks centered at 517 nm. It is anticipated that the silver and fluorescein as functionalized dopants for the phosphotungstate hollow sphere structure would provide this material with corresponding multi properties. Control experiments indicated that the fluorescein plays a key role in the formation of hollow sphere structure. Hence, The codoping strategy is proposed to be general in endowing polyoxometalates nanomaterials with new structures, new functions and therefore in this case the potential applications in bioimaging, fluorescent chemical sensors, antibacterial or optoelectronic devices.
