Abstract

Recently, room temperature phosphorescence (RTP) materials have drawn considerable attention owing to their extended emission lifetime, substantial Stokes shift, heightened environmental sensitivity, etc. Carbon dots (CDs) are RTP material candidates that possess outstanding optical stability, good water solubility, nontoxic nature, and facile functionalization. Herein, we developed a simple and rapid method for preparing heteroatom-doped RTP CDs and regulating their luminescent properties via controlling the doping element and structure. The obtained CDs can be excited by both ultraviolet and visible light. An obvious improvement in RTP lifetime and yield as well as modulation of emission wavelength can be achieved. The maximum lifetime of the obtained RTP CDs reaches 754.05 ms, with a phosphorescence quantum yield of 16.78%, and the emission wavelength of RTP can be effectively controlled from cyan to yellow. These outstanding properties ensure their utilization in areas like information encryption and anticounterfeiting.

可见光激发硼氮共掺杂碳点的室温多色磷光

近年来，室温磷光（RTP）材料因其具有较长的发光寿命、较大的斯托克斯位移、较高的环境敏感性等优点而备受关注。碳点（cd）是RTP材料的候选材料，具有优异的光学稳定性、良好的水溶性、无毒性质和易于功能化。本文开发了一种简单快速的制备杂原子掺杂RTP CDs的方法，并通过控制掺杂元素和结构来调节其发光性能。所制得的CDs可被紫外光和可见光激发。在RTP寿命、产率和发射波长调制方面均有明显改善。所制得的RTP CDs的最大寿命达到754.05 ms，磷光量子产率为16.78%，发射波长可由青色到黄色有效控制。这些突出的特性确保了它们在信息加密和防伪等领域的应用。
