I have synthesized a composite of ZnO and In2O3 with variations in ZnO content. In Raman , what is the peak observed at 130 cm-1?

Dear all, I have noticed, as the ZnO content increases, the Raman intensity at 100cm-1 also increases. However, there is a peak nearby at 130 cm-1, which I could not find in any paper related to...
