Materials have been exhibited homogenous surface morphologies, broading /-or diffusion of bonding energy peaks relative elemental values and a high UV/Visible absorption tendency in the wave length range 400 nm- 850 nm range with the optical energy band gaps 1.37 and 1.42 respectively. Subsequently, UV/Visible reflectivity property in the wave length range 250 nm to 320 nm for these materials has also been discussed.}, journal = {International Journal of Physical and Mathematical Sciences}, volume = {7}, number = {1}, year = {2013}, pages = {70 - 74}, ee = {https://publications.waset.org/pdf/9686}, url = {https://publications.waset.org/vol/73}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 73, 2013}, }
