We have examined the effects of Bi concentration, annealing in air, and addition of reducing agent on the near-infrared (NIR) emission of Bi-doped TiO2–ZnO–B2O3–Al2O3 (TZBA) glass. Since the decay constants of the NIR emission are independent of the Bi concentration and the preparation conditions, it is expected that a small part of Bi species can act as effective activators in the glass. Annealing affects the blue shift and broadening of the NIR emission. The change in the bandwidth upon Bi or AlN addition can be explained from the viewpoint of the viscosity of the glass melt, which seems to be one of the important factors for obtaining broadband-emitting materials.
