中文摘要 | a series of eu2+ and eu2+/tb3+ activated novel ba3lana(po4)(3)f phosphors have been synthesized by traditional solid state reaction. rietveld structure refinement of the obtained phosphor indicates that the ba3lana(po4)(3)f host contains three kinds of ba sites. the photoluminescence properties exhibit that the obtained phosphors can be efficiently excited in the range from 320 to 430 nm, which matches perfectly with the commercial n-uv led chips. the critical distance of the eu2+ ions in ba3lana(po4)(3)f:eu2+ is calculated and the energy quenching mechanism is proven to be dipole dipole interaction. tunable blue-green emitting ba3lana (po4)(3)f:eu2+,tb3+ phosphor has been obtained by co-doping eu2+ and tb3+ ions into the host and varying their relative ratios. compared with the tb3+ singly doped phosphor, the codoped phosphors have more intense absorption in the n-uv range and stronger emission of the tb3+ ions, which are attributed to the effective energy transfer from the eu2+ to tb3+ ions. the energy transfer from the eu2+ to tb3+ ions is demonstrated to be a dipole-quadrupole mechanism by the inokuti-hirayama (i-h) model. the eu2+ and tb3+ activated phosphor may be good candidates for blue-green components in n-uv white leds. |
