Infrared transient absorption spectra for excited transition of excitons and biexcitons in CuCl

Takaaki Yoshioka, Kensuke Miyajima, Masaaki Ashida +1 more

Abstract Infrared transient absorption (IRTA) spectra for excitons and biexcitons in CuCl bulk crystal have been measured by pump‐probe spectroscopy. The IRTA peak energy of the exciton agrees with the transition energy between Rydberg 1s to 2p states reported in one‐ and two‐photon absorption measurement. On the other hand, the IRTA peak energy of the biexcitons locates in energy higher than that of the excitons, which is reasonable by taking hydrogen molecule model into account. In addition, our results support the enhancement of the transition energy between 1s and 2p states in quantum dots compared to the bulk case. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Observation of optical Stark effect between 1s - 2p exciton levels in CuCl single crystal

S Efumi, Yuki Uchibori, Jun Ishihara +1 more

We measured the transient reflection spectra induced by infrared light for a CuCl single crystal using pump-probe spectroscopy. A Stark shift of the 1 s exciton was observed using light with a near resonant energy between the 1 s and 2 p exciton levels. The amount of energy shift due to the Stark effect was obtained from the absorption spectra calculated using the Kramers–Kronig transform. We investigated the energy shift of 1 s excitons with respect to the excitation density. This is the first published report on the Stark effect of 1 s exciton associated with the internal energy levels of the excitons in CuCl crystal.
