Abstract:The detection of trace amounts of explosive like trinitrotoluene (TNT) is an important issue in the prevention of terrorist attacks. Surface enhanced Raman scattering (SERS) spectroscopy has become a powerful detection technique for identification of minute amounts of analytes. This thesis presents data of TNT in solution, deposited on a nanostructured gold surface, which is heated up to 60 °C. The observed changes in the microscopy images and in the SERS spectra are explained by evaporation, phase transition and decomposition of the TNT molecules. The impact of temperature dependence of SERS effect is studied on a chemisorbed 4-Nitrothiophenol monolayer. To minimize the evaporation of TNT molecules, a self-assembled monolayer of mercaptohexanol (MCH) was inserted between plasmonic surface and TNT.
Keywords:surface enhanced Raman spectroscopy, explosives, temperature dependence, microscopy, evaporation, phase transition, decomposition

Title:Vpliv temperature na površinsko ojačan ramanski spekter 2, 4, 6 trinitrotoluena
Abstract:Zaznavanje sledi eksplozivov, kot je trinitrotoluen (TNT), je pomembno področje pri preprečevanju terorističnih napadov. Površinsko ojačana ramanska spektroskopija (SERS) je postala močna detekcijska tehnika za identifikacijo majhnih količin analitov. V magistrskem delu so predstavljeni podatki o TNT raztopini, naneseni na nanostrukturirano zlato površino, ki je ogreta do 60 °C. Zaznane spremembe, ki jih opazimo na podlagi mikroskopskih slik in SERS spektrov, razložimo s pomočjo izhlapevanja, faznega prehoda in razgradnje TNT molekul. Vpliv temperaturne odvisnosti na SERS učinek je bil raziskan na kemisorbiranem monosloju 4-nitrothiophenol molekul. Da bi zmanjšali izhlapevanje TNT molekul, je bil med plazmonsko površino in TNT vstavljen samosestavljiv monosloj mercaptoheksanola (MCH).
