Red, green, and blue emissions are observed simultaneously for an organoterbium complex that displays remarkable multiphoton upconversion when excited by a near‐infrared light source. The system undergoes two nonlinear optics processes simultaneously: second and third harmonic generation (SHG: red emission; THG: blue), and four‐photon upconversion (green) for excitation at λ ≈1.26 (see diagram).
