Abstract

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.
