Homogeneous glasses were formed in the Cr 2 O 3- TeO 2- B 2 O 3- SrF 2 system, up to 20 mol% Cr 2 O 3. For these glasses, IR and Raman spectral measurements were carried out in order to elucidate the local structure. The results showed that BO 3 and BO 4 are the main structural units of the glass system and the chromium ions are located in the network. It was evidenced the presence of TeO 3 and TeO 4 units as possible structural units in our glasses.
