| 英文摘要 | Three new absorption bands, appearing around 670, 865 and 980 nm, are observed in bafcl:eu2+ phosphors. they are ascribed to f aggregates formed by association of f centers or by trapping of electrons to the primary f-n(+) (n = 2,3,4) centers. the growth curves of f and f-aggregated centers are similar and may be divided into three stages. the photostimulated luminescence (psl) decays by stimulation into the absorption bands of f centers and of f aggregates are different; the former decay logarithmically and the latter decay hyperbolically. some non-radiative processes related to f aggregates, such as electron migration, occur accompanying the psl process, which may reduce the psl efficiency and sensitivity of the phosphors.
