WebEmission and excitation spectra of the Eu 3+ -doped BaBi 2 B 4 O 10 phosphors were investigated for the first time, where it was shown that characteristic lines are attributed to the intraconfigurational 4f-4f transitions. The optimal concentration for the BaBi 2-x Eu x B 4 O 10 phosphors is x = 0.4, after which a luminescence intensity decreases. WebOct 19, 2024 · These are called Characteristic X-Rays.

WebCharacteristic X-Rays The most energetic X-ray emission comes when a vacancy in a K shell (n =1) is filled by an outer electron. Removal of a 1s electron from a neutral atom raises it to the highest energy state represented by 1s1s −1 or 1 2 S 1/2 or K I. Removal of a 2s electron (2s2s −1) gives rise to L 1 state (2 2 S 1/2 ).
