| 中文摘要 | the temperature-dependent luminescence of sr(1.7)eu(0.3)m(x)ceo(4.15+x/2) (m=li(+), na(+), k(+), x=0, 0.3) samples was investigated and discussed in the temperature range from 303 to 573 k. it is found that the thermal quenching temperature of samples decreases with li(+)-/na(+)-doping but increases with the incorporation of k(+). we suggest that these observations are resulted from two factors. one is that the incorporation of li(+)/na(+)/k(+) ions reduces the strength of potential field at the o(2-) sites, and then results in a red-shift of the eu-o charge transferband. the other is that delta r expands with li(+)-/na(+)-doping but shrinks with k(+)-doping. we consider that it is a feasible way to adjust the temperature-dependent luminescence properties of materials by introducing appropriate impurities.
