Abstract

The upconversion luminescence of Er3+/Yb3+ ions is researched in a novel transparent oxyfluoride borosilicate glass and glass ceramics under 980-nm excitation. Fluoride nanocrystals Ba2YF7 are successfully precipitated in glass matrix, which is affirmed by the X-ray diffraction results. Compared with the parent glasses, significant enhancement of upconversion luminescence is observed in the Er3+/Yb3+ codoped transparent glass-ceramics, which may be due to the variation of coordination environment around Er3+ and Yb3+ ions after crystallization. The possible upconversion mechanism is also discussed.
