【 摘 要 】

Thermoluminescence (TL) characteristics of NaYF₄ crystals doped with Sm³⁺ have been studied after ð›�?-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.
