摘要：
Ba2YF7: Ho3+/Yb3+ nanocrystals embedded in transparent glass–ceramics were fabricated by the traditional melt-quenching technique. Impressively, self-crystallization occurred during the formation of precursor glasses, which can be confirmed by X-ray diffraction (XRD) patterns. After further heat treatment, enhanced up-conversion emission and prolonged lifetimes appear due to higher crystallinity. When the different concentrations of Ce3+ ions were doped into Ba2YF7: Ho3+/Yb3+nanocrystals, the red and green emissions of Ho3+ show tunable behavior under 980-nm excitation.
