Photoluminescence and excited states dynamics of Tm2+-doped CsCa(Cl/Br)3 and CsCa(Br/I)3 perovskitesPlokker, M.P. (author), Biner, D. A. (author), Dusoswa, N. (author), Dorenbos, P. (author), Krämer, K. W. (author), van der Kolk, E. (author)In this study, we systematically vary the Cl/Br and Br/I ratios in CsCaX<sub>3</sub>:Tm<sup>2+</sup> (X = Cl, Br, I) and hereby gradually shift the positions of the Tm<sup>2+</sup> 4f<sup>12</sup>5d<sup>1</sup>-levels as relative to the two 4f<sup>13</sup> levels. At low temperatures up to five distinct Tm<sup>2+</sup> 4f<sup>12</sup>5d<sup>1...journal article 2021

(author)The prospect of using Tm<sup>2+</sup>-doped halides for luminescence solar concentrators (LSCs) requires a thorough understanding of the temperature dependent Tm<sup>2+</sup> excited states dynamics that determines the internal quantum efficiency (QE) and thereby the efficiency of the LSC. In this study we investigated the dynamics in CaX<sub...journal article 2021
