Functional silica nanoparticles are of particular interest in photonics and biotechnologies. On page 90 , Tangi Aubert, Stéphane Cordier, Fabien Grasset, and co‐workers report the synthesis of new luminescent ZnO‐Cs 2 [Mo 6 Br 14 ]@SiO 2 nanoparticles. The co‐encapsulation in a silica matrix of two complementary luminophores, ZnO nanocrystals and [Mo 6 Br 14 ] 2‐ cluster units, results in nanoparticles with tunable emission properties. Depending on the excitation wavelength, the nanoparticles show different colors of emission. If associated with a blue light‐emitting diode (LED), the nanoparticles produce a very broad emission spectrum covering almost the entire the visible range, thus affording the emission of white light.
