| 中文摘要 | photoluminescence (pl) and cathodoluminescence (cl) properties of ln(3+) (ln = tb, dy, eu, tm, ce) and mn2+-activated kcagd(po4)(2) (kcg) phosphors were investigated. under uv excitation, kcg:tb3+, kcg:dy3+, kcg:eu3+, kcg:tm3+, and kcg:mn2+ samples exhibit the characteristic emission of the activators, respectively. by altering doping activators and adjusting their relative doping concentrations in the kcg host, we obtained white emission in kcg:tm3+, tb3+, eu3+, kcg:tb3+, mn2+, eu3+, kcg:tb3+, eu3+, and kcg:dy3+, eu3+ samples under the excitation of 275 or 356 nm uv. besides, there exist three energy transfer pairs in the kcg host, i.e., ce3+ -> tb3+, ce3+ -> dy3+, and ce3+ -> mn2+. upon excitation at 280 nm, the absolute quantum yield of the optimized kcg:ce3+, tb3+ is 90.6%. under the low-voltage electron beam excitation, the cl properties of kcg:ln(3+)/mn2+ phosphors have been investigated in detail, and a variety of colors can be obtained in these samples. all of the results of this study reveal that the as-prepared kcg:ln(3+)/mn2+ phosphors have good luminescent intensity under uv and the low-voltage electron beam excitation, especially kcg:ce3+, tb3+ samples, making these materials have potential applications in white-light leds and field emission display devices. |
