摘要

Abstract

Phosphorescent carbon nanodots (CNDs) have generated enormous interest recently

and the CND phosphorescence is usually located in the visible region

while ultraviolet (UV) phosphorescent CNDs have not been reported thus far. Herein

the UV phosphorescence of CNDs was achieved by decreasing conjugation size and in-situ spatial confinement in a NaCNO crystal. The electron transition from the

to the

orbit of the N atoms within the CNDs can generate one-unit orbital angular momentum

providing a driving force for the triplet excitons population of the CNDs. The confinement caused by the NaCNO crystal reduces the energy dissipation paths of the generated triplet excitons. By further tailoring the size of the CNDs

the phosphorescence wavelength can be tuned to 348 nm

and the room temperature lifetime of the CNDs can reach 15.8 ms. As a demonstration

the UV phosphorescent CNDs were used for inactivating gram-negative and gram-positive bacteria through the emission of their high-energy photons over a long duration

and the resulting antibacterial efficiency reached over 99.9%. This work provides a rational design strategy for UV phosphorescent CNDs and demonstrates their novel antibacterial applications.
