Popis:	The application of thermoluminescence technique in radiation dosimetry spans field of health physics, biological and geological sciences and personnel monitoring; this led to the search for new compositions with desirable dosimetric properties. In the present work, CaSrAl2SiO7:Tb3+ and CaSrAl2SiO7:Ce3+,Tb3+ phosphors were prepared by solid-state reaction method and their TL properties were studied in detail. The comparison of their TL results showed that co-doping of Ce3+ ions enhanced TL response of CaSrAl2SiO7:Tb3+ phosphors; this was also verified from measurement of TL emission spectra of the samples. Optimized glow curves were analysed and TL parameters were extracted from Chen’s method. Co-doped CaSrAl2SiO7:Ce3+,Tb3+ phosphor is found to be useful in dosimetric application.
