Abstract

In₂O₃ nanoparticles with particle sizes of 5-50 nm were synthesized by a simple, cost effective and environmental friendly route using indium acetylacetonate and Aloe vera plant extracted solution. The precursor was characterized by TG-DTA to determine the thermal decomposition and crystallization temperature which was found to be at above 350 °C. Nanoparticles are formed after calcination the dried precursor of In ₂O₃ in air at 400-600°C for 2 h. Structural, morphological and optical properties of the synthesized nanoparticles were characterized. XRD and TEM analysis showed that the In₂O₃ samples are cubic with particle sizes of 5-50 nm. The morphology and size of In₂O₃ materials were affected by the calcination temperature. The prepared In₂O₃ nanoparticles showed a strong PL emission in the UV region. The strong emissions of In ₂O₃ are attributed to the radioactive recombination of an electron occupying oxygen vacancies with a photo-excited hole. The present work proves that the Aloe vera plant-extracted solution synthesis is a new useful method using cheap precursors for preparation of In₂O₃ nanoparticles.
