Strongly Enhanced Free-Exciton Luminescence in Microcrystalline CsPbBr_3 Films (Condensed Matter: Electronic Structure, Electrical, Magnetic and Optical Properties)
スポンサーリンク
概要
- 論文の詳細を見る
The luminescence properties of CsPbBr_3 films prepared via the amorphous phase by crystallization are dominated by free-exciton emission, and only a weak trace of emission due to trapped excitoris was observed, in contrast to the case of bulk CsPbBr_3 crystals. In particular, the films in the microcrystalline state show by more than an order of magnitude stronger free-exciton emission than in the polycrystalline state. The enhanced free-exciton emission is suggestive of excitonic superradiance.
