Thermally evaporated in ₂O ₃ nanoloquats with tunable broad-band emissions

We describe synthesis of In ₂O ₃ nanoloquats grown by thermal evaporation under different oxygen flow rates and temperatures. Gold nanoparticles were used the catalysts and were dispersed on the silicon wafer to assist growth of In ₂O ₃ nanoloquats. The nanostructures of In ₂O ₃ nanoloquats were characterized by scanning electron microscopy, transmission electron microscopy and X-ray diffraction. The photoluminescence study reveals that In ₂O ₃ nanoloquats could emit different broadband luminescence peaks in the range of 410-620 nm by tuning different oxygen flow rates and temperatures. The wide tuning range in the emission peaks of In ₂O ₃ nanoloquats has potential in applications of white light illumination.
