My study focuses on solid state physics in relation to nanoscale. Preparation and characterization of the structural, optical, and luminescent properties of rare earth doped compound semiconductors comprises of my PhD dissertation work. In the work done, the host compounds are oxides that, in varying proportions, consist of transition metals including zinc and cadmium. They have fascinating optical and emission characteristics. Due to its potential applications, there is ongoing interest in the development of luminous zinc oxide with single (TM/RE) and double (TM and/or RE) doping. In my PhD dissertation, La-Cd and Sm-Cd ions substituted ZnO compounds synthesized using the sol-gel method and investigated their structural, morphological, optical (band gap, refractive index) changes and luminescence features.
