Abstract:
In this work, carbon nanotubes were prepared by chemical vapor deposition (CVD) and doping by different molarity of titanium dioxide Ti O2 (0.00, 0.05 and 1.5) molar. UV/VIS spectrophotometer technique was used to investigate the optical characteristics of all samples. The maximum absorbance value is 1.82 ( a.u ) for carbon + Ti O2 (1.5 molar )and the minimum value is 0.99 ( a.u ) for carbon + Ti O2 (0.00 molar ) , absorbance of CNT samples that treatment by Titanium dioxide was increased due to Ti O2 molarity increased at 258 nm . The maximum value of refractive index is (2.79) for all samples that made at wave length range (345 -368) nm. The samples have a direct electronic transition, and the optical energy gab decreased with molarity increased. This results leads to that Titanium dioxide is a good material to enhance the optical properties of carbon nanotubes.
