Excitonic enhancement and excited excitonic states in cspbbr3 halide perovskite single crystals

HIGHLIGHTS

  • who: Anna Yu. Samsonova and collaborators from the Department of Photonics, Saint-Petersburg State University, ulUlyanovskaya, Saint-Petersburg, Russia have published the article: Excitonic Enhancement and Excited Excitonic States in CsPbBr3 Halide Perovskite Single Crystals, in the Journal: Materials 2023, 16, 185. of /2023/
  • what: In this work, a study of the reflectivity from the CsPbBr3 single crystal in the 4-150 K temperature range is presented. Excited 4 of 8 excitonic states follow the same trend but become indistinguishable at temperatures above 80 K. To describe the spectral shape of the observed n=1 . . .
