Abstract
A lanthanide chelate is linked to a noble metal substrate at a proximity wherein the substrate enhances a fluorescent emission of the lanthanide by at least 20-fold when the chelate is illuminated at an excitation wavelength that induces a transition in the lanthanide that results in the fluorescent emission.
