EFFECT OF DIFFERENT METHODS OF EXTRACTION ON OPTICAL PROPERTIES FOR DYE LANTANA CAMERA

Article history: Received: 01 JUL, 2019 Accepted: AUG, 2019 Available Online: 25 DEC, 2019 This work focuses on the two methods of extraction for dye plant Lantana Camara (ethanol and water), thin film was synthesized from two solvents by spin coating method on glass substrates. Theses dyes were characterized by the measurement of Fourier transform infrared spectrophotometer FTIR, the result showed that the film had the chemical structure for flowers of lantana camara of two methods in rang (4000-400 cm -1 ). The measurement the optical properties of the films were studied by using UV spectrophotometer. The range absorbance spectrum has been recorded at wavelength with in the (300-1000) nm. The optical absorption (A) for the peak of ethanol was 0.93 in the wavelength 330 nm while for extraction water was 0.7 in the wavelength 330 nm ,determined the optical constants such, as absorption coefficient (α) was less than of 10 4 that value of ethanol and water extraction , an extinction coefficient (k) was low value between (0.2-0.25) .and was found optical energy gap from extraction water (2.4) eV ,and the optical energy gap of extraction of ethanol was found (2.25) eV.
