Study of optically stimulated luminescence dosimetric properties of submicron BaSO4: Eu Phosphor

In this context dosimetric properties of submicron BaSO4: Eu phosphor have been studied. To reduce the grain size of the material to submicron level, top-down approach (ball billing) has been adopted. The phosphor showed good optically stimulated luminescence (OSL) properties. The OSL properties of the phosphor were altered due to the particle size reduction on ball milling. Ball milling affected the kinetics of OSL Processes. OSL dose response of the phosphor has been increased up to 13 kGy on ball milling which makes it useful in high dose dosimetric applications.
