Pressure Dependence of Absorption Edge,Luminescence Peak and Raman Frequency in Wolffram's Red Salt
スポンサーリンク
概要
- 論文の詳細を見る
Absorption, luminescence and Raman spectra are studied under high pressurein Wolffram's red salt. It is suggested that the quasi-one-dimensional electron-phonon system is continuously changed by pressure from a moderate couplingstate at atmospheric pressure to a weak coupling state, not by decreasing theelectron-phonon coupling energy, but by increasing the transfer energy. Thedecrease of the phonon energy of the symmetric stretching vibration of Cl aroundPt" and the rapid decrease of the energy gap with the pressure increase up to0.2 GPa are thought because the Pi"-Cl distance would increase with increasingpressure as the Pt"-Pt" distance decreases.
