For the first time, hollow PbTe nanospheres with diameters of 80−140 nm have been prepared in an ether/glycerol microemulsion system and PbTe single‐crystalline nanotubes with diameters of 60−80 nm have been synthesised in a homogeneous ethanol/glycerol system. They can be facilely controlled via a solvothermal process without any additional catalysts and templates. Two different template mechanisms are discussed herein. The Raman and far infrared spectra of the samples have been investigated at room temperature. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
