چکیده مقاله
MgSO4:Dy andMgSO4:Cu nano-rods(NRs)weresynthesizedforthe first timebysemico-precipitation
method. X-raydiffraction(XRD),scanningelectronmicroscopy(SEM)andenergydispersivespectro-
metry (EDS)wereutilizedforsamplecharacterization.Theoptimumamountofdysprosiumandcopper
concentrations wereobtainedbothat0.1mol%inMgSO4:Dy andMgSO4:Cu NRs.Tm-Tstop and compu-
terized glowcurvedeconvolution(CGCD)methodswereusedforidentifyingthenumberofcomponent
glow peaksandkineticparametersofthesynthesizedNRs.Initialriseandvariableheatingratemethods
werealsousedtoensurethereliabilityofobtainedkineticparameters.ResultsshowthattheTLsensi-
tivity ofMgSO4:Dy isabout7timesmorethanthatofmagnesiumsulfatedopedwithCu.TheTLdose
response ofMgSO4:Dy andMgSO4:Cu NRsarelinearuptoabsorbeddoseof10KGy.OtherTLdosimetry
characteristicsoftheproducedNRsarealsopresentedanddiscussed.
