Abstract

A range of germanate glasses containing praseodymium and chlorine was prepared. The optical absorption edges and infrared absorption spectra were measured. It is found that a small addition of PrCl3 to GeO2 glasses decreases the optical energy gap, but further addition of PrCl3 increases the optical energy gap. The main infrared absorption bands in the GeO2-PrCl3 glasses are related to those characteristic of the GeO2 component.
