Abstract

original image

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-Cs2[Mo6Br14]@SiO2 nanoparticles. The co-encapsulation in a silica matrix of two complementary luminophores, ZnO nanocrystals and [Mo6Br14]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.
