Abstract
The fabrication of a new class of cerium (Ce) and Ce/Au co-doped nano-phase separated alumina-phospho-silica glass based optical fibres through modified chemical vapour deposition (MCVD) process coupled with solution doping technique is presented along with study of their radiation response behavior under 60Co-gamma radiation source at 635nm wavelength. The sensitivity of both Ce doped and Ce/Au co-doped fibres are found to be 0.4643dB/m/Gy and 0.4360dB/m/Gy, respectively. The experimental results show that Ce doped and Ce/Au co-doped optical fibres have good response to radiation exposure which can be useful as a radiation sensor for fibre optic based personal dosimetry applications.
