1.5-μm Intraband Transitions in PbSe Quantum Dots
スポンサーリンク
概要
- 論文の詳細を見る
Intraband transitions around 1.5 μm are studied in PbSe quantum dots at room temperature. Femtosecond pump-probe measurements reveal induced absorption by photoexcited carriers up to higher energy levels and its relaxation. A dominant decay component has a decay time of 10–40 ps, which is determined by the relaxation of carriers at the lowest absorption peak. The induced absorption is observed in a broad spectral range between 0.77 and 2.5 eV.
