Spectral, Optical and Electrical Characterization Of 1-(2-Hydroxyethyl)-2-Methyl-5-Nitroimidazole (Metronidazole) Single Crystal

Abstract

Single crystal of 1-2-(hydroxyethyl)-2-methyl-5-nitroimidazole (Metronidazole) is a well-known antibacterial drug, was grown by slow evaporation method. The spectral and optical characterization of the crystal was determined using UV-Visible spectroscopy and photoluminescence study. The crystal show very good transparency of 95% in the entire visible region. The optical band gap energy E_g was calculated from the tauc’s plot as 2.44 eV. On screening the material for photoluminescence, four emission peaks are observed at 360 nm (3.44 eV), UV radiation; sharp peak at 380 nm (3.26 eV), visible violet; 490 nm (2.53 eV), visible blue and sharp peak at 525 nm (2.36 eV) due to the emission of green light. This study confirms that the drug metronidazole shows excellent optical properties.
