Luminescence lifetime of Ce(Ⅲ)for Ce_(0.9)RE_(0.1)P_5O_(14),where RE denotes rare earth ions other than Ce(Ⅲ),was measured by means of the time-correlated single photon counting technique.It has been found that thelifetime data are capable of elucidating the enhancement or quenching of cerium(Ⅲ)luminescence by alien REions(other than Ce)in doubly doped cerium pentaphosphate crystal.
