Biosynthesis of nanoparticles was an important area in the field of nanotechnology which has economic and eco-friendly over chemical and physical methods of synthesis. In present work, synthesis of CeO2 nanoparticles was achieved using 1 mM Cerium (III) nitrate hexahydrate (Ce(NO3)3. 6H2O through the extract of Hybanthus enneaspermus (H. enneaspermus) as reducing as well as capping agent. Green synthesis of CeO2 NPs retained the cubic phase which was confirmed by X-ray diffraction studies. TEM images showed that the NPs possessed spherical shape and average particle size of 20-30 nm. EDAX studies determined the elemental compositions were identified for Cerium and oxygen. The FT-IR spectra confirmed the Ce-O stretching bands at 457 cm-1 for the CeO2 NPs. The band gap of the CeO2 NPs was estimated at 2.9 eV from the UV-Vis spectrum. From the photoluminescence measurements, the broad emission composed of six different bands were found. The green synthesized CeO2 NPs showed dose dependent response against breast cancer MCF-7 cell line (LD50-10 μg/ml).
