Abstract

A benign room temperature synthesis process has been developed to fabricate peroxy niobates with controllable composition and morphology. X-ray diffraction and scanning electronic microscopy were used to monitor the change of the phase composition and corresponding microstructure of the obtained niobates. Furthermore, UV/Vis spectra were used to study the optical properties of these ammonium and potassium peroxy niobates. The results showed that these peroxy niobates with {O₂} units present larger bandgap than those with {O₂F} units. Photoluminescence results well demonstrated that the Nb group environment is sensitive to its optical properties, which offers a marvelous chance for its further applications, such as sensors.
