Bismuth oxide nano particles were prepared by Sol Gel method at 100 °C. From the powder XRD pattern, the estimated average crystallite size of as prepared, 300 °C calcinations and 600 °C calcinations are 64.02 nm, 27.47 nm and 17.03 nm respectively. The observed percentage of transmittance is 51% for as prepared, 75% for 300 °C calcinations and 84% for 600 °C calcinations. Fourier transform Infrared studies confirm that Bismuth was bond with oxygen (Bi-O) which confirmed by the peak at 574 cm−1. Atomic % and weight % of Bismuth and Oxygen in Bismuth Oxide were revealed by Energy dispersive X-ray analysis. Surface morphology consists of rod like morphology for as prepared sample and oval shape like morphology with number of breaking pieces for 600 °C calcined sample which was disclosed by scanning electron microscope analysis. The major high intensity PL emission peak was observed at 360 nm in the Ultraviolet region. [ABSTRACT FROM AUTHOR] |
