nanocrystals were prepared by high-temperature melting and heat treatment method.Comparison with the as-prepared glass
Dy
3+
doped oxyfluoride glass ceramics exhibit higher emission intensity excited at 386 nm and the intensity ratio between blue light and yellow light emission increases gradually with the heat treatment temperature
which indicates that Dy
3+
ions have participated into the precipitated GdF
3
nanocrystals.Under the excitation of 980 nm laser diode
the upconversion luminescence intensity increases gradually with the heat treatment temperature and the upconversion luminescence peaks appear apparent Stark splitting phenomenon
which also demonstrates Er
3+
ions have entered into the precipitated GdF
