Journal of alloys and compounds, 2007•ElsevierSingle crystal samples of lead telluride doped with cerium were made using the Bridgman
method. Far infrared reflectivity spectra in the temperature range from 10 to 300K are
presented. The experimental data were numerically analyzed using a fitting procedure
based on the plasmon–phonon interaction model and optical parameters were determined.
Two additional local modes were observed at about 138 and 337cm− 1. The origin of these
local vibrational impurity modes was discussed.
