Abstract

Mg doped nano-SnO is synthesized via ball milling technique for 5 hours. The Mg concentration is varied when doped with SnO. Each concentration goes through heat treatment and direct leaching process at same time. The characterized of samples using XRD, UV-Vis and PL. XRD tracks the progress of nano-SnO formation during milling. The band gap determined using Uv-Vis Spectroscopy shows that as dopant concentration are high, the band gap decreases because of the dopants that filled the gap between conductance and valence band. Also, PL shows the intensity behavior of dopant concentration. Intensity is dependent with crystalline size of nanoparticles.
