介绍了一种发光性质依赖于水接触的新型纳米发光材料———基于超级碳点的发光“纳米炸弹”。在甲苯溶液中,这种“纳米炸弹”光致发光很弱;当遇见水后,“纳米炸弹”分解为小的碳点,光致发光显著增强。将“纳米炸弹”与纸复合可应用在喷水荧光打印和汗孔成像。目前,大部分智能荧光材料存在光稳定性差,潜在的生物毒性,制备成本高,或与传统喷墨打印不兼容等缺点。本文报道的碳基纳米材料没有(或很少有)这些缺点,并可实际应用在光信息存储,司法鉴定和医疗检测等领域。

Developing smart luminescent materials is desirable for different fluorescence imaging applications . Here, we report a new luminescent material called luminescent “nano-bombs” based on supra-carbon-nan-odots, whose luminescence depends strongly on water contact .That kind of “nano-bombs” show weak emis-sion in toluene and decompose when meeting water , resulting in strong photoluminescence .With these “nano-bombs” we demonstrate water-jet printing luminescence patterns and mapping human sweat pore patterns in the supra-carbon-nanodots-coated paper .While by now most of smart luminescent materials suffer , more or less, low photostability , potential biotoxicity , high cost or poor compatibility with traditional inkjet printing technology , such a carbon-based nanomaterial without ( or with much less ) those deficiencies may find practi-cal applications in optical information storage , forensic and healthcare .
