description [Display omitted] •Formation of Sb2-xMnxTe3 nanocrystals with average size around of 7.5 nm.•EPR results confirmed the 2+ oxidation of Mn ions and that they were incorporated in the Sb2Te3 NCs.•Influence of Mn concentration as a dopant in semiconductor Sb2Te3 nanocrystals grown in a host glass matrix.•The interstitial incorporation of Mn causes significant changes in the Sb2Te3 characteristic vibrational modes. Vibrational modes property variations of diluted magnetic semiconductor nanocrystals of Sb2xMnxTe3 grown in a glass host system were investigated. Transmission electron microscopy images and energy dispersive X-ray analysis confirm the size, interplanar distance and composition of these NCs. Electronic paramagnetic resonance spectra confirm the incorporation of manganese ions in the Sb2Te3 crystal lattice due to the six absorption lines. Moreover, changes in Mn-Mn interactions are observed as xMn-concentration increases. The Raman- and IR-active vibrational modes of quintuple layer changes of the Sb2-xMnxTe3 NCs give strong evidence of the incorporation of Mn2+ ions in Sb2Te3 NCs.
