Europium doped silver tungstates α-Ag2−3xEuxWO4 (x = 0, 0.0025, 0.005, 0.0075 and 0.01 mol) were synthesized by the coprecipitation method at 90 °C for 30 minutes. PL spectra showed a broad band related to the [WO6] group and characteristic narrow peaks due to the f–f transitions of Eu3+ as a result of efficient energy transfer from the matrix.

ABSTRACTA family of low melting temperature tin fluorophosphate glasses that can incorporate certain organic compounds has been under investigation. The glasses are comprised principally of SnF2, SnO, and P2O5; the addition of small amounts (< 5%) of Pb improves chemical durability. These materials are dense, reasonably water durable, and easily fabricated. Photoluminescence properties of glasses doped with pyrene, POPOP, stilbene 420 and several other organic molecules were studied. All of the doped glasses exhibited intense photoluminescence. Pyrene doped glass was found to have monomer-triplet and dimer-excimer pyrene species present, depending on the dopant concentration. Scintillation properties of the glasses were also investigated. Generally a very fast (~1 ns or less) but weak luminescence was observed. Results of these studies suggest that higher concentrations of the dyes must be incorporated into the glass and more efficient energy transfer from the glass host to the organic fluor must be attained for these materials to be useful as fast scintillators.
