Cerium(IV) based samples namely cerium phosphate (CP), cerium molybdate (CM) and cerium phosphomolybdate (CPM) in the present study were obtained as yellow solids. They show maximum absorption in the ultra-violet region. Ligand to metal double-charge transfer transitions, are responsible for the bright colours of the materials. The absoption edge around 250nm for the samples is an indication of the presence of band gap in the materials. The study reveals that the band gap of the materials can be tuned by incorporating different anions. The band gap energy of the synthesized samples obtained were in the range 1.2 3.5 eV.
