Abstract
    In this paper, the electronic structure, absorption coefficient and reflectivity index of tP10-FeB4 at different temperatures were calculated by density functional theory (DFT), and the conclusions are obtained in the following. The valence band maximum (VBM) and conduction band minimum (CBM) of tP10-FeB4 are mainly composed of Fe-3d and B-2p electronic states. What’s more, with the increase of temperature, the redshift phenomenon appears in absorption spectrum and reflectivity spectrum, which is consistent with the band gap width change?regulation. Finally, in the ultraviolet region, tp10-FeB4 has a good absorption spectrum and is a kind of potential ultraviolet absorption material.
