Photoluminescence Study of Tin Oxide-Zinc Oxide Nanocomposites

Undoped and Cu 2+ doped (SnO2)1-x(ZnO)x nanocomposites were synthesized using a simple microwave assisted solvothermal method with ethylene glycol as solvent. The as-prepared samples were calcinated at 500 0 C for 1hr. The optical studies were carried out using Photoluminescence measurements. A small shift in the peak position was observed for doped samples when compared to undoped samples. The shifting was due to the incorporation of dopant into the host matrix and also coupled with the variation of band gap energies of the nanocomposites. The results obtained were reported and discussed herewith.
