STUDY OF OBSERVATION FLUORESCENCE WITH DOMAIN WAVELENGTH BASED ON SPECTROSCOPY FLOURESCENCE FOR MATERIAL IDENTIFICATION

Abstract

A research on the Study of Observation Fluorescence with Domain Wavelength Based on Spectroscopy Flouresensi for Material Identification. The sample at this object are olive oil, sandalwood oil, and cem-ceman oil, the result of measurement for olive oil, obtained energy absorption (E 1 ) and excitation energy (E 2 ) respectively each 0,388 . 10 -18 Joule dan 0,383 . 10 -18 Joule , the wavelength of absorption (λ 1 ) and the excitation wavelength (λ 2 ) each amounting to 512 nm and 518 nm absorption intensity (I 1 ) and Fluorescence Intensity (I 2 ) each amounting to 76 and 73 . For Sandalwood oil, gained energy absorption ( E 1 ) and excitation energy (E 2 ) respectively each 0,360 . 10 -18 Joule dan 0,357 . 10 -18 Joule , the wavelength of absorption (λ 1 ) and the excitation wavelength (λ 2 ) each amounting to 552 nm and 557 nm , the absorption intensity (I 1 ) and Fluorescence Intensity (I 2 ) each amounting to 42 and 41 . For cem - ceman oil, gained energy absorption (E 1 ) and excitation energy (E 2 ) respectively each 0,39 . 10 -18 Joule and 0,386 . 10 -18 Joule , the wavelength of absorption (λ 1 ) and the excitation wavelength (λ 2 ) each amounting to 510 nm and 514 nm absorption intensity (I 1 ) and Fluorescence Intensity (I 2 ) each 45 and 43 . . Measurements were made with a detector ( Ocean Optics USB HR2000 ) . Keywords : fluorescence, wavelength specktrum, detector, essential oils, olea europia.l
