The influence of synthesis methods on the morpho - structural and luminescent characteristics of rare earth silicate phosphors

Cerium activated yttrium silicate (Y2SiO5:Ce) phosphors were prepared by two different wet-chemical synthesis routes namely: simultaneous addition of reagents (SimAd) and solution combustion (SC) using yttriumcerium nitrate and urea as starting materials. TEOS or SiO2 fume were used as Si sources. A...

Description
Summary:Cerium activated yttrium silicate (Y2SiO5:Ce) phosphors were prepared by two different wet-chemical synthesis routes namely: simultaneous addition of reagents (SimAd) and solution combustion (SC) using yttriumcerium nitrate and urea as starting materials. TEOS or SiO2 fume were used as Si sources. A comparative study regarding the morpho-structural and luminescent properties of Y2SiO5:Ce phosphors is presented. The influence of the silicon source, same as the firing temperature on the samples characteristics were discussed. TG-SDTA, FT-IR, SEM, XRD and photoluminescence investigations were used to characterize the precursors and the corresponding phosphors.
