文摘
- •
A High temperature TL emission is observed for the SrSO4:Eu nanophosphor, which is not reported so far.
- •
The phosphor has very high TL sensitivity to both gamma rays and X-rays including diagnostic and therapeutic beams.
- •
Well defined, sharp, single isolated TL glow curves suitable for dosimetric applications.
- •
Fading rate of the phosphor is better than that of the commercially available standards TLD-200 and TLD-400.
- •
Easy and cost effective preparation method.
