Vijayakrishnan, V and Kulkarni, GU and Rao, CNR (1990) Valence state of bismuth and thallium in superconducting cuprates: a $Bi-L_3$ and $TI-L_3$ X-ray absorption spectroscopic study. In: Modern Physics Letters B, 4 (7). pp. 451-461.Full text not available from this repository.
Based on a $Bi–L_3$ edge X-ray absorption spectroscopic study of superconducting bismuth cuprates and model $Bi$ compounds, it is shown that $Bi$ is essentially in the 3 + state in the cuprates. $TI–L_3$ absorption edge studies a number of thallium cuprate superconductors along with those of model compounds show some evidence for the occupancy of the $TI-6s$ band, but $Tl^3+$ is the prepondarant species. $Cu$ K-edge studies of the thallium cuprates show that $Cu$ is essentially in the 2+ state.
