Homogeneous distribution of semicrystalline ceria in polymethylmethacrylate has been reported. The ceria has been prepared by sonochemical method, in situ. The as-prepared composite was characterized by XRD, TEM, DSC and TGA methods. An average size of the ceria is found to be ∼ 5 nm by XRD and TEM measurements. The photonic band gap has been measured as 3.55 eV, which is in well agreement with the ceria crystals, indicating absence of a quantum size effect.
