| 中文摘要 | a series of single-phase phosphors based on knaca2(po4)(2) (kncp):a (a = ce3+, eu2+, tb3+, mn2+, sm3+) have been prepared via the pechini-type sol-gel method. photoluminescence (pl) and cathodoluminescence (cl) properties of ce3+-, eu2+-, tb3+-, mn2+-, and sm3+-activated kncp phosphors were investigated. for the a singly doped kncp samples, they exhibit the characteristic emissions of the a activator. na+ ions exhibit the best charge compensation result among li+, na+, and k+ ions for ce3+-, tb3+-, and sm3+-doped kncp samples. the energy transfers from ce3+ to tb3+ and mn2+ ions as well as eu2+ to tb3+ and mn2+ have been validated. the emission colors of kncp:ce3+/eu2+, tb3+/mn2+, na+ samples can be adjusted by energy transfer process and changing the tb3+/mn2+ concentration. more importantly, white light emission in kncp:eu2+, mn2+ system has been obtained. the kncp:tb3+, na+ sample shows tunable luminescence from blue to cyan and then to green with the change of tb3+ concentration due to the cross-relaxation from d-5(3) to d-5(4). a white emission can also be realized in the single-phase kncp host by reasonably adjusting the doping concentrations of tb3+ and sm3+ (reddish-orange emission) under low-voltage electron beam excitation. additionally, the temperature-dependent pl properties of as-prepared phosphors reveal that the kncp host has good thermal stability. therefore, the kncp:a (a = ce3+, eu2+, tb3+, mn2+, sm3+) phosphors could be regarded as good candidates for uv w-leds and feds. |
