On the optical band gap in certain ternary phosphate and TeO2 based glasses

Popis výsledku v původním jazyce

An emphasis is placed on the fact that the correct determination of the optical band gap using the Tauc or Davis- Mott model requires the use of the correct samples thickness for the optical transmission measurements. For 46 heavy metal oxide glasses based on P2O5 or TeO2 the optical band gap values were determined using the Davis - Mott model from the classical optical absorption measurements on the samples with the thickness varying from 0.5 to 4 mým. For PbO-ZnO-P2O5 glasses and for heavy metal oxideglasses 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.
