Far infrared reflectivity spectra of single crystal Pb 0.85Sn0.15Te doped with Ni were measured in the temperature range between 10 K and 300 K. Analysis of the experimental spectra was made using a fitting procedure based on the modified model of plasmon-phonon interactions and the optical parameters were calculated. Two local modes were observed and their origin was discussed. © Carl Hanser Verlag GmbH & Co. KG.
