CuInSe 2 quantum dots are reported here for the first time. The highly crystalline nanoparticles of CuInSe 2 and also of CuSe were prepared by reaction in tri‐ n ‐octylphosphine oxide (TOPO), producing TOPO‐capped particles that are close to monodisperse. Transmission electron microscopy shows that the particles are spherical, with clear lattice fringes (see Figure).
