This paper presents X ray excited TL spectra of magnesium borate doped with either single rare earth ions Dy or Tin, or co-doped with Dy/Tm, Tm/Mn or Dy/Tb. Intrinsic emission from the host material is in the UV/blue region at similar to375 nm, with a tail extending to 200 nm. The main dosimetric peak is detected at similar to180degreesC but slight differences are noted between the glow peak maxima from the different rare earth ions and there were changes following thermal treatments. The results are discussed according to the interaction between trapping and rare earth sites.
