Au/Ag alloyed nanostructures exhibit a bright three‐photon luminescence upon excitation by a femtosecond laser, and have an intensity level one order of magnitude higher than pure Au or Ag nanoparticles. As Y. Xia, J.‐X. Cheng, and co‐workers describe in their Communication on page 3485 ff., the excitation is outside the range of plasmon resonance, thus enabling bioimaging with negligible photothermal toxicity.
