Luminescence properties of Eu3+ doped gadolinium aluminum garnet phosphors

Gd3Al5O12 (GdAG) doped with Eu (Gd1-xAG: Eux) was synthesized by using sol gel method with the doping concentration of Eu as 0.1, 0.5 and 1.0 mol%. The prepared material was sintered at 1100 °C.GdAG was doped with to check its utility as material for the white light emission. The synthesized materia...

Description
Summary:Gd3Al5O12 (GdAG) doped with Eu (Gd1-xAG: Eux) was synthesized by using sol gel method with the doping concentration of Eu as 0.1, 0.5 and 1.0 mol%. The prepared material was sintered at 1100 °C.GdAG was doped with to check its utility as material for the white light emission. The synthesized material was characterized by using XRD, FT-IR and Fluorescence spectroscopy. XRD analysis revealed that crystal phase remained same and there was no change in the crystallite size on doping. XRD results were supported by FTIR spectra. The formation of metal oxygen bonds were confirmed by multiple absorption peaks in the range 400–740 cm−1 in FT-IR spectrum. Florescence spectra show the broad emissions in the visible region showing Eu doped GdAG as a good alternative phosphor for white light source.
