In the present work aluminium oxide nanoparticles are synthesized using leaf extract of Ocimum sanctum. The synthesized sample was characterized by XRD, HR-TEM, UV-Vis, FTIR and PL. It is found that aluminium oxide nanoparticles synthesized by leaf extract are stable and show good optical properties. This method of synthesis is less toxic and cost of synthesis is low as compared to other chemical and physical methods. By XRD pattern phase of synthesized aluminium oxide nanoparticles is confirmed and the average particle size is found to be 19.43 nm. By HR-TEM analysis, the particle size of synthesized nanoparticles ranges from 18 nm to 25 nm. By UV-visible spectroscopy the energy band gap is found to be 2.55 eV. By FTIR analysis presence of Al-O band and biofunctional group is confirmed. Photoluminescence spectroscopy confirmed the energy band gap of as synthesized alumina nanoparticles is 2.19 eV. Hence, from the present study, it is concluded that aluminium oxide nanoparticles synthesized by plant leaf extract are good semiconductors.

In the last decades, the idea of green nanotechnology has been expanding, and researchers are developing greener and more sustainable techniques for synthesizing nanoparticles (NPs). The major objectives are to fabricate NPs using simple, sustainable, and cost-effective procedures while avoiding the use of hazardous materials that are usually utilized as reducing or capping agents. Many biosources, including plants, bacteria, fungus, yeasts, and algae, have been used to fabricate NPs of various shapes and sizes. The authors of this study emphasized the most current studies for fabricating NPs from biosources and their applications in a wide range of fields. This review addressed studies that cover green techniques for synthesizing nanoparticles of Ag, Au, ZnO, CuO, Co3O4, Fe3O4, TiO2, NiO, Al2O3, Cr2O3, Sm2O3, CeO2, La2O3, and Y2O3. Also, their applications were taken under consideration and discussed.

Nanotechnology is an escalating field, which has an growing impact in each and every sector. There are many ways for synthesizing nanoparticles but biosynthetic route of nanoparticle synthesis is emerging as a new and safer alternative to the conventional methods. Ocimum basilicum Lamiaceae (OBL) is an age old herb native to Southeast Asia and Central African countries. These plants are generally known to be used in different cuisines world-wide. The aroma emitted from the leaves and the twigs of the fresh and dried plants are well known to have insect repellent property. Estragole, citronellal, limonene and nerolidol are the natural volatile compounds present in the basil leaves which acts as repellents. This plant is also widely used as a scent through which it netted its title Queen (basileus) of aromatic herbs. In present study the Green synthesis of some metal oxide nanoparticles have been synthesized by Ocimum Basilicum-Lamiaceae (Thiru Neetru Pathilai).These methods are completely green methods, free from toxic and harmful solvent. Note and measure visual observation of the nanoparticle solutions, preliminary test of electrical conductivity(EC), pH change of the reaction mixture and total dissolved suspend(TDS) in the reaction were measured and recorded.
