Abstract
A method of determining a property within a subterranean formation comprises introducing silica nanoparticles into a well; obtaining a sample of a fluid produced from the well; and analyzing the sample for presence of the silica nanoparticles, wherein the silica nanoparticles comprise a core, a donor chromophore, an acceptor chromophore, and an outer silica shell; the donor chromophore and the acceptor chromophore being selected such that an emission spectrum of the donor chromophore overlaps with an absorption spectrum of the acceptor chromophore.
