Abstract:
Carbon Nanotube (CNT) is tubular form carbon with diameter as small as 1nm
and length of few nanometers to microns. CNT is configurationally equivalent to
a two dimensional graphene sheet rolled into a tube. The aim of research was
manufacturing single walled carbon nanotube and calculation its absorbance,
transmission and energy gap. In this research the optical properties investigated.
Three different types of single walled carbon nanotube (lampblack, kohl and
frankincense) weighted by using electric balance and dissolved in four
hydrocarbon solutions benzene, acetone, methanol and ethanol in order to obtain
12 samples of single walled carbon nanotube to study their optical properties
such as absorption and transmission. The absorbed spectrum and energy gap
were studied using USB Spectrophotometer which gives higher absorptivity
wavelength for lampblack at 477 nm in methanol solution, and higher
absorbance for kohl in benzene solution and equal 1.20 au and higher
transmission for frankincense in acetone solution equal 29.4 %, higher energy
gab of lampblack, kohl and frankincense in methanol solution and equal 2.53 eV.
