Thermoluminescence properties of optical fibers doped with RE+3 (RE=Sm, Nd) ions subjected to X-ray irradiation

This paper describes the thermoluminescence properties of RE+3(RE=Nd, Sm) doped optical fiber SiO2. The samples were exposed to 6 MV X-ray irradiation at dose ranging from 0.5 to 4 Gy at hospital Sultan Ismail, Johor Bahru, Malaysia using the LINAC accelerator. After exposure and a certain delay of...
