概要
- 論文の詳細を見る
Various aspects of luminescence in β-ZnP_2 have been investigated at low temperatures. Formation of exciton molecules is confirmed under the CW resonance excitation into the lowest 1s triplet exciton absorption band. The exciton molecule emission band M appears at a moderately weak laser power. Low energy component C_<L1> of the singlet luminescence comes from the anti-Stokes acoustic phonon scattering of the triplet excitons. From the outgoing resonance of the LO Raman line, it is confirmed that the high energy component C_<L2> has many strong phonon sidebands, while low energy component C_<L1> has no sideband. Furthermore, a novel luminescence C_T resulted from the anti-Stokes scattering of the triplet excitons has been found. From detailed excitation spectra, we can deduce some of the relaxation paths of the exciton polaritons.
