✦ Synopsis

By simple room temperature broad band time-resolved spectroscopy it was possible to discriminate different Eu'+ spectra in SnO, monolithic gels obtained by a sol-gel synthetic route. Nanocrystalline domains of the cassiterite-like SnO*: Eu could be easily identified in the transparent medium. From X-ray diffraction profiles a mean particle radius of 2.2 nm was estimated.
