摘要： New oxyfluoride glasses and glass ceramics co-doped with Nd^{3+}, Yb^{3+} and Ho^{3+} were prepared. The upconversion of infrared radiation into green fluorescence has been studied for Nd^{3+}, Yb^{3+} and Ho^{3+} in the transparent oxyfluoride glass ceramics. At room temperature very strong green upconversion luminescence due to the Ho^{3+}: ({}^5F_4, {}^5S_2)→{}^5I_8 transition under 800 nm excitation was observed in the glass ceramics. The intensity of the green upconversion luminescence in a 1mol% YbF_3-containing glass ceramic was found to be about 120 times stronger than that in the precursor oxyfluoride glass. The reason for the highly efficient Ho^{3+} upconversion luminescence in the oxyfluoride glass ceramics is discussed. The upconversion mechanism is also investigated.

Abstract: New oxyfluoride glasses and glass ceramics co-doped with Nd$^{3+}$, Yb$^{3+}$ and Ho$^{3+}$ were prepared. The upconversion of infrared radiation into green fluorescence has been studied for Nd$^{3+}$, Yb$^{3+}$ and Ho$^{3+}$ in the transparent oxyfluoride glass ceramics. At room temperature very strong green upconversion luminescence due to the Ho$^{3+}$: ($^5$F$_4$, $^5$S$_2$)→$^5$I$_8$ transition under 800 nm excitation was observed in the glass ceramics. The intensity of the green upconversion luminescence in a 1mol% YbF$_3$-containing glass ceramic was found to be about 120 times stronger than that in the precursor oxyfluoride glass. The reason for the highly efficient Ho$^{3+}$ upconversion luminescence in the oxyfluoride glass ceramics is discussed. The upconversion mechanism is also investigated.
