Application to Water Monitoring
Decreased performance of Sr ScintEx resin
Efficient Scintillation Detection
High absorptivity for high energy electromagnetic radiation or particles, e.g. in UV and deep UV
Efficient Förster resonance energy transfer (FRET) Efficient harvesting of the absorbed energy and its concentration on the
emitting centers
High quantum yield – i.e., the ratio of the # of emitted photons to the # of absorbed photons
Large Stokes Shift – to minimize self-absorption Maximum of the emission wavelength to match the maximum
absorption wavelength of photodetector typically achieved by application of a mixture of primary and
secondary fluorophores Optical transparency in visible range High stability of properties under harsh conditions of chemical,
