Thermoluminescence studies of BaMgAl10O17 doped with Eu phosphors

BaMgAl10O17:Eu, phosphors have been synthesized in air atmosphere by high temperature solid state reaction. Two well defined thermoluminescence (TL) glow peaks are shown at 180 and 330 deg C under gamma irradiation. The TL emission spectra of samples reveal two emission peaks at 617 and 895 nm. Thes...

Description
Summary:BaMgAl10O17:Eu, phosphors have been synthesized in air atmosphere by high temperature solid state reaction. Two well defined thermoluminescence (TL) glow peaks are shown at 180 and 330 deg C under gamma irradiation. The TL emission spectra of samples reveal two emission peaks at 617 and 895 nm. These changes are probably due to electronic charges and sizes of Eu(3+) dopant ions.
