Synthesis, thermoluminescence and dosimetric properties of La-doped zinc borates

► Powder samples of undoped and La-doped zinc borate were prepared by the nitric acid method. ► TL properties and dependence on the dose of beta radiation of the samples have been investigated. ► The dose responses of the powder samples showed good linearity. ► The results showed that ZnB2O4:La sample can be a promising TLD material for dosimetric applications.
