Abstract:

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.
