Paper Abstract

Temperature study of Raman scattering in polycrystalline guanidinium iodide C(NH2)3I is presented. Temperature dependences of the Raman intensity and full width at half maximum (FWHM) for the two most temperature sensitive bands -- 510 cm-1 and 1528 cm-1 -- have been investigated. A significant decrease in intensities and an increase in FWHM of the modes studied are observed with an increase in temperature. Moreover, for both temperature dependences we have also observed very large hysteresis while the temperature was decreasing.
