We observed a high strength near-infrared luminescence in Bi-doped KAlCl4 polycrystalline material. Luminescence dependence on the excitation wavelength and temperature of the sample was studied. Our experimental results allow asserting that the luminescence peaked near 1 lm belongs solely to Bi? ion which isomorphically substitutes potassium in the crystal. It was also demonstrated that Bi? luminescence features strongly depend on the local ion surroundings.
