中文摘要sr3in(po4)(3) (sip):ce3+/tb3+/mn2+ phosphors have been prepared via a solid state reaction process. under uv excitation, there are three energy transfer (et) pairs in the sip host, i.e., ce3+ -> tb3+, ce3+ -> mn2+, and tb3+ -> mn2+. both of the ets from ce3+ to tb3+ and from ce3+ to mn2+ in the sip host have been demonstrated to be resonant type via a dipole-quadrupole mechanism, and the critical distance (r-c) calculated by the quenching concentration method and spectral overlap method, respectively, were investigated. by the et of ce3+ -> tb3+, ce3+ -> mn2+, and tb3+ -> mn2+ the emitting colors of the studied samples could be adjusted from blue to green, from blue to orange-red, and from green to green-yellow, respectively. more importantly, under low-voltage electron beam excitation, the cl spectra of the sip:ce3+, mn2+ samples cover the whole visible light region, resulting in a white light emission. additionally, the cl properties of sip:ce3+/tb3+/mn2+ phosphors have been investigated in detail. the results reveal that the as-prepared phosphors have good cl intensity and cie coordinate stability under electron beam bombardment. compared with the commercial green phosphor zno:zn, sip:7% ce3+, the 10% tb3+ sample has a higher cl brightness. in conclusion, tunable light with high quantum yield (68%) has been obtained in sip:ce3+/tb3+/mn2+ phosphors by utilizing the principle of energy transfer and properly selecting the activator contents under uv and electron beam excitation.
