Abstract Novel blue LED excitable Ce3+-doped alkaline-earth sulfide nanocrystals are exploited for selective and sensitive Fe3+ ions sensing in this work. The detection limit is calculated to be as low as 92.5 nM, which is better than most previous ultra-violet light excited fluorescence probes. The decreased radiative probability of the Ce3+: 5d by the NC surface environmental variation activates the sensing capability.

蓝色 LED 激发的 Ce3+ 掺杂碱土硫化物发光纳米晶体用于选择性和灵敏的 Fe3+ 离子传感

摘要 在这项工作中，新型蓝光 LED 可激发 Ce3+ 掺杂碱土硫化物纳米晶体被用于选择性和灵敏的 Fe3+ 离子传感。经计算，检测限低至 92.5 nM，优于大多数以前的紫外光激发荧光探针。由于 NC 表面环境变化，Ce3+: 5d 的辐射概率降低，激活了传感能力。
