Abstract

doped transparent germanate glass ceramics embedded with LaF

nanocrystals were successfully prepared

via

melt-quenching and subsequent thermal treatment. The luminescent properties of the as-prepared glass and the glass ceramics were investigated in detail. The X-ray diffraction results prove that the crystalline phase precipitated in the glass matrix was pure LaF

crystal and the crystal size was between 16 nm and 21 nm. Under the excitation of 377 nm ultraviolet light and X-ray

glass ceramics embedded with LaF

nanocrystals show much intense green emission than Tb

doped germanate glass

and the green emission intensity increases with the increment of thermal treatment temperature and time. The maximum integrated X-ray excited luminescence intensity of the glass ceramics is about 40.3% of that of Bi

crystal which is the commercial scintillating crystal. Our research shows that Tb

doped germanate glass ceramics embedded with LaF

nanocrystals have potential application prospects in X-ray detection.
