A new approach to synthesize self‐doped colloidal Cu 3−x P NCs with controlled size and localized surface plasmon resonance absorption is reported. These Cu 3−x P NCs show ultrafast exciton dynamics and huge optical nonlinearities due to plasmonic resonances, which afford the first demonstration of plasmonic Cu 3−x P NCs as simple, effective, and solution‐processed nonlinear absorbers for high‐energy Q‐switched fiber laser.
