Elaboration and Luminescent Properties of Eu/Tb Co‐Doped GdPO4‐Based Glass Ceramics for White LEDs
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 (5D4→7F5 of Tb3+) and red (5D0→7F2 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.
