摘要：
Single crystal samples of lead telluride doped with samarium were produced using the Bridgman method. Far infrared reflectivity spectra in the temperature range 10 K - 300 K are presented and numerically analyzed using a fitting procedure based on a modified plasmon-phonon interaction model. The optical parameters were determined and three local modes of samarium were observed at about 167 cm(-1), 227 cm(-1) and 486 cm(-1).
