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 (E₁) and excitation energy (E₂) respectively each 0,388 . 10 ^-18 Joule dan 0,383 . 10 ^-18 Joule, the wavelength of absorption (?₁) and the excitation wavelength (?₂) each amounting to 512 nm and 518 nm absorption intensity (I₁) and Fluorescence Intensity (I₂) each amounting to 76 and 73. For Sandalwood oil, gained energy absorption ( E₁) and excitation energy (E₂) respectively each 0,360 . 10 ^-18 Joule dan 0,357 . 10 ^-18 Joule, the wavelength of absorption (?₁) and the excitation wavelength (?₂) each amounting to 552 nm and 557 nm, the absorption intensity (I₁) and Fluorescence Intensity (I₂) each amounting to 42 and 41. For cem - ceman oil, gained energy absorption (E₁) and excitation energy (E₂) respectively each 0,39 . 10 ^-18 Joule and 0,386 . 10 ^-18 Joule, the wavelength of absorption (?₁) and the excitation wavelength (?₂) each amounting to 510 nm and 514 nm absorption intensity (I₁) and Fluorescence Intensity (I₂) each 45 and 43. . Measurements were made with a detector ( Ocean Optics USB HR2000 ) .
