Abstract

12CaO7Al

:Ce

(C12A7:

%Ce

) transparent ceramics were synthesized by a solid state method. Upon 350 nm UV excitation

a broad emission band located around 440 nm can be observed and it can be attributed to the transitions from 5d

5/2

and

7/2

of Ce

respectively. It can be seen that the emitting intensity increases with the increasing of Ce

doping concentration. When the mole fraction of Ce

exceeds 0.7%

other impurities appear. To enhance the emitting intensity

C12A7:0.5%Ce

transparent ceramics were prepared by a self-propagating combustion method. For the samples annealed in H

ambient

the scintillation properties

such as the emitting intensity and decay time

are improved by controlling sorts and amounts of encaged anions in C12A7. The experiment results show that Ce

doped C12A7 might be a potential scintillation material.
