For 46 heavy metal oxide glasses based on P2O5 or TeO2 the optical band gap values were determined using the Davis – Mott model. For PbO-ZnO-P2O5 glasses and for heavy metal oxide glasses based on TeO2 the band gaps in the regions 4.6-5.39 eV and 3.14-3.61 eV, respectively, were found. Using the simplest version of the alloying model the band gaps for glasses PbO-ZnO-P2O5 in the region 4.11-5.78 eV and for heavy metal oxide glasses based on TeO2 in the region 3.02-3.75 eV were calculated.
