    • Abstract


      Thermoluminescence (TL) characteristics of NaYF4 crystals doped with Sm3+ have been studied after 𝛾-ray irradiation. Dependence of luminescence efficiency on Sm3+ concentration and radiation dose has been measured and possible applications of NaYF4 : Sm3+ as a novel phosphor for TL dosimetry have been investigated. The efficiency of 0.3 mole% Sm3+ doped NaYF4 crystal has been found to be maximum and comparable with commercial thermoluminescence dosimetric (TLD) materials.
