Near‐infrared‐emissive polymer‐carbon nanodots (PCNDs) are fabricated by a newly developed facile, high‐output strategy. The PCNDs emit at a wavelength of 710 nm with a quantum yield of 26.28%, which is promising for deep biological imaging and luminescent devices. Moreover, the PCNDs possess two‐photon fluorescence; in vivo bioimaging and red‐light‐emitting diodes based on these PCNDs are demonstrated.
