Near‐infrared (NIR) emissive materials are highly attractive for fluorescence bio‐imaging application. In article number 1905050, Songnan Qu and co‐workers develop NIR absorbing/emissive carbon dots via microwave assisted exfoliation. More importantly, a unique thermally activated up‐conversion NIR emission is observed under 808 nm continuous‐wave laser excitation.
Upconversion near‐infrared (NIR) fluorescent carbon dots (CDs) are important for imaging applications. Herein, thermally activated upconversion photoluminescence (UCPL) in the NIR region, with an emission peak at 784 nm, which appears under 808 nm continuous‐wave laser excitation, are realized in the NIR absorbing/emissive CDs (NIR‐CDs). The NIR‐CDs are synthesized by microwave‐assisted exfoliation...
