The photoluminescence of high purity n-type CdTe single crystals ( n = 2.9 x 1014 0 1 1 1~~) a t liquid helium temperature is studied at different excitation intensities. Emissions due to the recombination of free excitons and excitons bound to neutral donors, ionized donors, and neutral acceptors are discussed as well as the transitions of free carriers to various impurities. Other impurity related spectral features are observed within the range of 120 meV from the band edge and their origin is described in analogy to the present knowledge of the spectra of 111-V and other 11-VI compounds.Photolumineszenzspektren von reinem CdTe (Elektronenkonzentration = 2,9 x 1014 cm-s) werden bei Heliumtemperatur und in Abhangigkeit von der Anregungsintensitat gemessen. Die Emissionen, die auf Rekombinationen von freien Exzitonen, Exzitonen an neutralen und ionisierten Donatoren und an neutralen Akzeptoren zuriickzufiihren sind, und solche, die auf Ubergiinge freier Ladungstriiger an Storstellen zuriickzufiihren sind, werden diskutiert. Andere Teile der Spektren (bis zu 120 meV von der Bandkante) werden in Analogie zu Spektren von 111-V und anderen 11-VI Verbindungen interpretiert.
