We present here the Bi incorporation properties of GaSbBi layers grown by liquid phase epitaxy technique. Secondary ion mass spectroscopy technique indicates that Bi is distributed uniformly along the depth of the layer with slowly decreasing concentration away from the surface. Room temperature optical absorption measurements show a band gap lowering of 25 meV for a layer grown from a melt containing 1 at% Bi.
