Nanoparticles of CaSO4:Dy as a sensitive TL material for 100 MeV O7+ swift heavy ions

CaSO4:Dy nanoparticles synthesized by chemical co-precipitation method was irradiated with 100 MeV O7+ Swift Heavy Ions (SHI) in the fluences range from 1 x 1011 to 5 x 1012 ion/cm2. An XRD spectrum shows the orthorhombic phase with crystallite size around 65 nm. The TL dosimetric peak appeared at 5...

Description
Summary:CaSO4:Dy nanoparticles synthesized by chemical co-precipitation method was irradiated with 100 MeV O7+ Swift Heavy Ions (SHI) in the fluences range from 1 x 1011 to 5 x 1012 ion/cm2. An XRD spectrum shows the orthorhombic phase with crystallite size around 65 nm. The TL dosimetric peak appeared at 554 K which seems to be a deep level trap co-related with good linear dose response. These nanoparticles also revealed the good sensitivity along with low fading (4.3 % for 2 months). Finally, this results suggest that CaSO4:Dy nanoparticles can be used for the ion dosimetry.
