Eco-friendly Synthesis and Characterization of Nanostructure SnO2 Thin Films Using Citrus aurantifolia Peel Extract by Spin Coating Method

Nanotechnology is anticipated to open novel opportunities to prevent and fight against diseases using atomic scale tailoring of materials [1-3]. In the field of nanotechnology, the synthesis of nanoparticles of different sizes, shape, chemical compositions and controlled morphology with high dispersityis essential because they exhibit unique properties, which are not observed in bulk materials [3-5]. Nanoparticles play crucial roles in, Solar cell, photovoltaic, Photo catalytic, drug delivery, diagnostics, imaging, sensing, gene delivery, artificial implants and tissue engineering [6] and which has considerable attention because of their various applications. The green synthesis of SnO2 is evolving an important branch of nanotechnology. Recently, researchers have focused on biologically synthesized SnO2 because of its extensive applications in the development of new technology in the field of electronics, Solar cell, material science and medicine at the nanoscale [7]. Gendarussa vulgaris an important medicinal plant belongs to family apocynaceae and it is a perennial herb grown commercially for its alkaloids [8,9]. There are more than 70 alkaloids (mostly of indole type) that have been reported from different parts of Celeome Gynandra [10] and the major alkaloids are Vincristine and Vinblastine, which has anticancer property and used as a drug in the treatment of different cancers [11]. In India as well as other countries, tea made from the fresh leaf juice of G. vulgaris has been used by ayurvedic physicians for the treatment of certain skin problems such as dermatitis, eczema and acne [12-15]. The main aim of this study is to synthesize green SnO2 NP by using the reducing tin oxide the fresh aqueous leaf extract of the herbal plant citrus aurantifolia peel leaf extract. SnO2 NP synthesized by leaf extract results were compared to SnO2 NP synthesized using spin coating method of synthesis were are investigated and reported. The synthesized SnO2 films Different post sintered 100 °C and 200 °C for 25 minutes to investigate the phase transition and crystalline nature of materials. The synthesized materials were evaluated for the Solar cell applications [16].
