Sr3Ir4Sn13 is an interesting compound showing a coexistence of structuralphase transition and superconductivity. The structural phase transition at 147K leads to the formation of a superlattice. We performed optical spectroscopymeasurements across the structural phase transition on single crystal sample ofSr3Ir4Sn13. The optical spectroscopy study reveals an unusual temperatureinduced spectral weight transfer over broad energy scale, yielding evidence forthe presence of electron correlation effect. Below the structural phasetransition temperature an energy gap-like suppression in optical conductivitywas observed, leading to the removal of partial itinerant carriers near Fermilevel. Unexpectedly, the suppression appears at much higher energy scale thanthat expected for a usual charge density wave phase transition.
