Glasses with the composition of (99.5-chi)GeO2-chiWO(3)-0.5Bi2O3 (chi=3, 6, 9 mol%) and (99.5-psi)GeO2-psiBaO-0.5Bi2O3 (psi=3, 6, 9 mol%) were prepared. Their thermal, emission and absorption measurements were carried out. The near-infrared super broadband emission of the prepared samples peak around 1.3 microm
