The front cover image demonstrates plasmonic Au nanoparticle decorated, upconverting‐core@porous‐TiO 2 ‐shell microspheres that can absorb photons over a wide wavelength range from ultraviolet to near infrared. As reported by D. Ma and team on page 2950, this hybrid structure, rationally designed and realized to greatly benefit from plasmons and upconversion, shows significantly enhanced broadband, photocatalytic activity.
