Abstract
Silver-doped Li, Na and K aluminophosphate glasses and the corresponding basic glasses were prepared by traditional melting–quenching method. The influence of alkali metal oxides on the dosimetric properties was investigated under conditions of the same dosage and fixed silver concentration. The energy dependence, sensitivity and build-up time are related to alkali metal oxides. The atomic number, ionic radius and field strength of alkali ions have important effect on these dosimetric properties. Li aluminophosphate glass possesses the lowest fluorescence response and energy dependence; Na aluminophosphate glass owns the shortest build-up time; K aluminophosphate glass has the strongest fluorescence response, longest build-up time and highest energy dependence.
