Eu/Tb single-doped and co-doped oxyfluoride aluminosilicate glasses and glass ceramics containing GdPO4 nanocrystals were elaborated, and their structural and luminescent properties were investigated by X-ray diffraction, Transmission electron microscopy, excitation and emission spectra, as well as decay lifetime measurement. Excited by 350 nm light, a combination of blue (5d -> 4f of Eu2+), green (D-5(4)-> 7F5 of Tb3+) and red (D-5(0)-> F-7(2) of Eu3+) emissions emerges to achieve white emission in Eu/Tb co-doped precursor glasses and glass ceramics. Our research shows that Eu/Tb co-doped precursor glasses and GdPO4-based glass ceramics may be applied in lighting and luminescent aspects.
