Yttrium oxide; biosynthesis; nanostructure; Acalypha indica; antibacterial activity.

In this study, the synthesis of Yttrium oxide (Y₂O₃) nanoparticles was carried out from Acalypha indica leaf extract. The synthesized nanoparticles were characterized by using X-ray diffraction, scanning electron microscope, energy-dispersive X-ray spectrometer and transmission electron microscope for structural confirmation. The studies clearly indicate that the synthesized Y₂O₃ nanoparticle is a crystalline material with a particle size from 23 to 66 nm. Further analysis was carried out by Fourier transform infrared spectroscopy, to provide the evidence for the presence of Y–O–Y and O–Y–O stretchings in the synthesized Y₂O₃ nanoparticles. Thermogravimetric and differential scanning calorimetry analyses gave the thermal stability of Y₂O₃ nanoparticles. The results of the antibacterial studies conducted by using the synthesized Y₂O₃ revealed an increasing rate of antibacterial behaviour with pathogens.
