摘要：

The intensity of the absorption bands due to the hydroxyl (OH) vibrations in the spectrum of tellurite glasses was decreased by using tellurium tetrachloride (TeCl4) as a dehydrating additive. This additive is incorporated with the initial reagents of the glass. During synthesis, it reacts with the OH groups present in the glass melt by releasing gaseous hydrochloric acid. The low chloride content remaining in the different glasses after their synthesis negligibly modifies their thermal properties, their stability against crystallization, and their refractive index. Its low impact on the refractive index of the glasses was assessed in the mid-infrared thanks to an enhanced prism coupling system using a supercontinuum laser as light source.
