D. K. Pradhan, K. R. Nemade and S. A. Waghuley

Quantum size effect where the electronic and optical properties of solids are altered due to changes in the band structures, enhanced the surface/volume ratio in nano dimensions forces more than 33% of the atoms to be on the surface (for 10 nm dot 35), which drastically altering the physical properties. Consequently, optical study becomes crucial. CeO2 is an important rare earth metal oxide with the basis of several potential applications and implications. Nanostructured CeO2 was synthesized through single step chemical rout method. In present investigation, optical Band Gap and transition probability studied from UV spectrophotometer.
