Abstract
In the Research world nano particles plays a prominent role and have huge range of applications owing to their far-racing usage in different fields in the day to day life. The Semiconducting transition metal oxide Titanium dioxide (TiO2) aquirebetter ultraviolet obscure affect such as antibacterial and photocatalytic properties.It is an optimistic substance for the preparation of organic inorganic composite materials.It exists in crystalline as well as amorphous forms.In the present investigation Titanium dioxide (TiO2) powder was synthesized by Sol-gel techniqueby usingtitanium (4) isopropoxide (TTIP) as precursor. The XRD analysis affirms the phase and observed peaks are in good accord with the standard spectrum (JCPDS no.: 21-1272 and 21-1276). SEM affirms the particle size in the range of nano-meter.SEM image appears the arrangement of nano particle results in uneven arrangements with a size between 55.6 and 68.8 nm. Owing to its nano size the optical spectra confirm the enhancement of strong and prominent absorption and its spectrum band with maximum around 210 nm. FTIR recorded at room temperature in the region of 4000–400 cm−1 which confirms the functional groups. ESR confirms the magnetic properties of the sample.The magnetic resonance field of the ESR signal can be influenced by exchange interaction, soappear in a Dyson line shape and g factor with g = 2.
Keywords: XRD, ESR, SEM, Isopropoxide.
