[6a-C11-11] Enhancement of photoluminescence efficiency in PbBr-based perovskite thin films by mixing of divalent cations

〇Masanao Era¹ (1.Saga Univ.)

Keywords:PbBr-based perovskite, photoluminescence, cation mixing

We found that photoluminescence from PbBr-based perovskite films was enhanced by mixing of Sn cations; emission intensity of the PbBr-based perovskite film contain 20 % Sn cation is about 10 times larger than that of the PbBr-based perovskite film.
