Bandgap Energy and Optical Constants of Nano Crystalline PbSrBaTiO6 Ceramics
Anusha Mony, Sheelakumari Issac, Jayakumari Isac
Nano Crystalline Ceramic lead strontium barium titanate (PbSrBaTiO6) was synthesized thermo chemically by solid state method at different treating temperatures. A characteristic feature of all solid-state reactions is that they involve the formation of product phase (s) at the interfaces of the reactants. UV-VIS analysis of the sample was carried out. Tunable band gaps can be obtained by varying annealing temperatures. The optical constants of refractive index, extinction coefficient, normal-incidence reflectivity, and absorption coefficient showed systematic variation with temperature. The dispersion of refractive index was analyzed by the Wemple- Di Domenico single-oscillator model.
