The characteristics of topological insulators are manifested in both theirsurface and bulk properties, but the latter remain to be explored. Here wereport bulk signatures of pressure-induced band inversion and topological phasetransitions in Pb$_{1-x}$Sn$_x$Se ($x=$0.00, 0.15, and 0.23). The results ofinfrared measurements as a function of pressure indicate the closing and thereopening of the band gap as well as a maximum in the free carrier spectralweight. The enhanced density of states near the band gap in the topologicalphase give rise to a steep interband absorption edge. The change of density ofstates also yields a maximum in the pressure dependence of the Fermi level.Thus our conclusive results provide a consistent picture of pressure-inducedtopological phase transitions and highlight the bulk origin of the novelproperties in topological insulators.
