Crystallization plays a critical role in realizing the functionalization of glass materials. However, it is imperative to understand the microscopic mechanism of both the formation and the phase transitions of nanocrystals during heat processes. Here

The upconversion (UC) luminescence of Er3+-doped oxyfluoro-germanate glasses and glass ceramics is studied in terms of the Judd-Ofelt (J-O) theory. Using the least square method, three J-O intensity parameters (i.e., Ω2, Ω4, and Ω6) are determined
