A series of magnesium borate phosphors MgB4O7:Dy, MgB4O7:Mn and MgB4O7:Dy, Mn were prepared and their thermoluminescence (TL) emission spectra were measured. TL emission bands in 480, 575 and 660 nm at 200 and 360 °C were observed in the MgB4O7:Dy due to the transitions of the trivalent rare earth ions Dy 3+ . The glow peaks of broad wavelength band around ∼580 nm at 180 and ∼290 °C were observed...
