BeO ceramics were
synthesized by co-precipitation method. The luminescent behaviors of the BeO
ceramics prepared under different reaction conditions were investigated for
radiation dosimetry applications. The appropriate calcination temperature and
time for the sol-gel synthesis of BeO was determined as 1000 °C for 4 hours by
analyzing optically stimulated luminescence (OSL), thermoluminescence (TL)
sensitivities and radioluminescence (RL) emissions of the products. While
similar characteristic broad emission peak of BeO ceramics between 200 and 500
nm was obtained in RL spectra, an unexpected peak between 650 and 800 nm which
may be associated with the anion defects in BeO was observed. While highly
sensitive two TL peaks were observed up to 250 °C, low sensitive four TL peaks
were found up to 650 °C. The results showed that luminescent signals from the
BeO pellets produced at appropriate synthesis conditions were suitable for
radiation measurement applications in personal dosimetry.
