Niobium oxide(Nb2O5),as a functional oxide with unique structure and excellent properties,shows great potential in promoting the development of new-generation high-performance glass and glass-ceramics.This paper systematically reviews the recent research progress in niobium-containing glass and glass-ceramics.Firstly,the coordination state and network role evolution of Nb5+in different glass matrices(such as silicate,tellurite and phosphate)were deeply analyzed,and the structure-activity relationship of field strength matching principle and charge compensation mechanism on thermal stability and chemical durability is revealed.Secondly,the synergistic regulation mechanism of Nb5+in improving refractive index,enhancing third-order nonlinear optical response and optimizing rare earth ion luminescence is reviewed,and the tailoring effect of Nb-O-RE bonding topology on local crystal field is revealed.Furthermore,the crystallization kinetics based on the heredity of glassy structure and the revolutionary breakthrough of femtosecond laser-induced crystallization technology in realizing three-dimensional patterning and submicron precision of LiNbO3 ferroelectric crystal phase are discussed in detail,and the physical mechanism of periodic self-organization driven by laser-induced Marangoni convection is clarified.Finally,the future development trends of niobium-containing glass and glass ceramics in the fields of cross-scale computing design,new material system exploration and multi-functional integrated devices are prospected.The purpose of this paper is to provide a reference for the in-depth research and innovative application of niobium-containing glass and glass ceramics.
