GREEN SYNTHESIS AND CHARACTERIZATION OF ZINC OXIDE NANOPARTICLES USING CASSIA ARTICULATE FLOWER EXTRACT

Zinc oxide (ZnO) nanoparticles were prepared by using green synthesis method. The prepared nanoparticles were characterized by using Fourier transform infrared spectroscopy (FTIR). The wave number 828 cm- 1 indicated the presence of the zinc oxide nanoparticles. The average crystallite sizes were calculated by applying sheer equation on the base of XRD powder patterns of all samples and found to be in the range 38.11 nm. This is order in nanosize.

Experimental Procedure:-Preparations of Zinc Nanoparticles
The synthesis nanoparticles 50 ml of cassia articulate flower extract was taken and boiled to 60ºc using a stirrer heater. 5g of zinc nitrate was added to the solution as the temperature reached 60ºc. The mixture is then boiled in 1hour and then the mixture collected in a 100ml beaker and heated in an air heated furnace at 150ºc for 5 hours. A yellow colored powder was obtained and this was carefully collected and packed for characterization purposes. The material was mashed in a mortar-pestle so as to get a finer nature for characterization.  Structural Studies:-X-ray diffraction: It shows that XRD pattern of the zinc oxide nanoparticle obtained by green synthesis method. The major phase corresponds to the (200), (220),(221) lattice plane. The (hkl) values are agreed well with the standard card of ZnO powder sample (JCPDS file no: 772414).The crystallite average size D of the prepared nanopowder can be calculated by using Debye Scherer's formula D = κλ/βcosѳ Where λ is the wavelength of X rays used (1.54060Ǻ), β is the full width at half maximum (FWHM) =0.24, 0.78, 1.18 and ϴ is the angle of diffraction. The crystallite average size of prepared nanopowder is found to be around 38.11 nm which is order in nanosized. [5]. Fig 2:-XRD Pattern of (Zno) nano particle.

Morphological Studies:-Scanning Electron Microscope:
SEM studies were revealed to visualize the size and shape of zinc oxide nanoparticles and show the typical brightfield SEM microscope of the synthesized zinc oxide nanoparticles. In this study, it was appeared with that most of rock in shape. [6] Fig 3:-SEM image of (ZnO) nanoparticles.

Edax (Energy Dispersive X-Ray Spectroscopy):
If confirm the structure element of aqueous extract of cassia articulate zinc oxide nanoparticles by green synthesis was carried

Conclusion:-
Fourier transforms infrared spectroscopy (FTIR). The wave number 828 cm-1 indicated the presence of the zinc oxide nanoparticles. The average crystallite sizes were calculated by applying sheer equation on the base of XRD powder patterns of all samples and found to be in the range 38.11 nm. This is order in nanosized. In accordance with the SEM image would like that rock in shape. The EDX indicated the presence of (Zr, Cl, and O). ZnO nanoparticles are prepared with help of the green synthesis method by using flower extract of Cassis Auricular. Green synthesis method is simple, non toxic.
