SERSTandem truncated nanocones resembling the 'Fairy Chimneys' rock formation in Cappadocia, Turkey, are proposed by N. A. Cinel and co-workers to provide a highly tunable double resonance substrate for use in surface-enhanced Raman spectroscopy.The nanocones, including two thin gold layers separated by a layer of SiO 2 , end up with resonances at laser excitation and Stoke's frequencies when properly designed as described on page 531.Such a tuning enables double-resonance substrates to perform better than their single-resonance counterparts. Eu 3+ DopantsM. Oh and co-workers create very uniform Eu 3+ -doped luminescent silica@coordination polymer core-shell microspheres through the growth of coordination polymers on silica surfaces.On page 561 they describe how the doping ratio within the coordination polymer shell is easily controlled by varying the amounts of metal ions used during the reactions.The following calcination and etching processes on silica@coordination polymer core-shell microspheres result in the production of doping ratio-controlled luminescent silica@Gd 2 O 3 :Eu core-shell and hollow Gd 2 O 3 :Eu microspheres.
