Superbroadband near-infrared (NIR) emission covering 1250 to $1680\mathrm{nm}$ wavelength has been obtained in praseodymium ( ${\mathrm{Pr}}^{3+}$ ) singly doped bismuth gallate glasses. The emission originates from the ${}^1{\mathrm{G}}_4\to {}^3{\mathrm{H}}_5$ and ${}^1{\mathrm{D}}_2\to {}^1{\mathrm{G}}_4$ transitions at 1330 and $1490\mathrm{nm}$ wavelengths, respectively, and is due to the extremely low phonon energy ( $\sim 690{\mathrm{cm}}^{-1}$ ) and the unique ligand field of the glasses. It is shown that the emission line shape can be modified by adjusting the ${\mathrm{Pr}}^{3+}$ concentration and the energy transfers involved. The results confirm that other than bismuth (Bi), chromium (Cr), nickel (Ni), and other chemical elements, ${\mathrm{Pr}}^{3+}$ singly doped system is a promising alternative in achieving superbroadband NIR emission.
