Abstract
In this paper we report synthesis of Magnesium substituted Zinc Oxide (Zn1-x Mgx O) nano-particles (~8-10nm) by low temperature solution route. We could reach upto x=0.075 without MgO getting segregated. Rietveld analysis of the XRD data confirms the Wurzite structure and a continuous compaction of the lattice as x increases. The bandgap also gets enhanced as x is increased and reaches a value of 4eV for x=0.075. The absorption also shows persistence of the excitoinc absorption on Mg substitution. The nanoparticles show near band edge photo luminescence (PL) at room temperature which shows blue shift on Mg incorporation.
