摘要：

The first-and second-order Raman phonon spectra of CsPbCl3 were measured in phase TV using Raman and resonance-Raman scattering. Twelve Raman active phonons were resolved at 32, 35.5, 42, 52, 72, 90, 110, 115, 121, 189, 200.5, and 375 cm(-1) and correlated to the phonon spectrum of CsPbCl3 in phase I. The highest frequency longitudinal optical mode is 375 cm(-1). (C) 1997 American Institute of Physics.
