InSeBr (Indium selenide bromide) is a ternary alloy layered semiconductor with an optical band gap of 2.1 eV in the bulk limit. It is one of the newest member of 2D semiconductor family and its' optical, electronic, or magnetic properties remain largely unknown. Based on our optical absorption spectroscopy datasets, its optical gap is at 2.1 eV and exhibits p-type electronic behavior. Selective area electron diffraction (SAED) datasets show it crystallize in monoclinic (P21/c) with lattice parameters a=0.71 nm, b=0.75nm, and c=0.83nm; b=~118.2 degrees.
