Cs x O 19 (x= 0.0, 0.05, 0.10), calcium copper titanate (CCTO) CaCu 3 Ti 4− y Al y O 12 (y=
0.0, 0.1, 0.2) and reduced graphene oxide (rGO) have been prepared. XRD patterns shows
the presence of single phase nanocrystalline SrM and CCTO which is further supported by
Raman spectroscopy and FTIR analysis. The presence of secondary phase such as α-Fe 2
O 3, CaTiO 3, and CuO has not been observed. Characteristics absorption bands of Cs …
