Abstract
A combination of chemical and thermal annealing techniques has been employed to synthesize a rarely reported nanocup structure of Mn doped ZnO with good yield. Nanocup structures are obtained by thermally annealing the powder samples consisting of nanosheets, synthesized chemically at room temperature, isochronally in a furnace at 200–500 °C temperature range for 2 h. Strong excitonic absorption in the UV and photoluminescence (PL) emission in UV–visible regions are observed in all the samples at room temperature. The sample obtained at 300 °C annealing temperature exhibits strong PL emission in the UV due to near-band-edge emission along with very week defect related emissions in the visible regions. The synthesized samples have been found to be exhibiting stable optical properties for ∼10 months which proved the unique feature of the presented technique of synthesis of nanocup structures.
