High-dose ther moluminescence dosimetry properties of novel zinc oxide nano phosphors synthesized by a solution combustion\nmethod in a glycine-nitrate process are presented for the very first time in this work. Sintered particles with sizes ranging between\n?500 nmand ?2 ????mwere obtained by annealing the synthesized ZnO at 900?C during 2 h in air. X-ray diffraction patterns indicate\nthe presence of the ZnO hexagonal phase, without any remaining nitrate peaks observed. The rmoluminescence glow curves of\nZnO obtained after being exposed to beta radiation consists of two maxima: one located at ?149?C and another at ?308?C, the latter\nbeing the dosimetric component of the curve. The integrated TL fading displays an asymptotic behavior for times longer than 16 h\nbetween irradiation and the corresponding TL readout, as well as a linear behaviour of the dose response without saturation in the\nstudied dose interval (from12.5 up to 400Gy). Such features place synthesized ZnOas a promising material for high-dose radiation\ndosimetry applications.
