چکیده انگلیسی
This work presents an alternative method to prepare rare-earth doped lanthanum aluminates materials for thermoluminescent (TL) dosimetry applications. Modified Pechini´s method was using to prepare praseodymium doped LaAlO3 powders. LaAlO3:Pr3+ powders were prepared using La(NO3)3·6H2O, Al(NO3)3·6H2O, Pr(NO3)3·6H2O, citric acid, and ethylene glycol. The solution was heated to 80 °C for its polyesterification reaction. The obtained powders were submitted at different thermal treatment from 700 up to 1600 °C. The structural and morphological characterizations were carried out using X-ray diffraction (XRD) and scanning electron microscopy techniques. TL glow curves of the X-ray irradiated samples showed one peak for europium and praseodymium dopants, meanwhile for powders doped with dysprosium ion showed two peaks. The technique is low cost, faster and it produces homogeneous particles can be used as thermoluminescent phosphors.
