Abstract

Infrared emission spectroscopy(EMS) has been known as an useful method for analysing thin organic films on metal substrates which have high reflectivity[1,2]. However, it is difficult to obtain spatial resolution of a specimen, since the measurement by the conventional method is carried out by heating the sample above detector temperature using an electrical heating equipments. In this paper, a laser excitaion method was examined instead of using an electrical heater. The emission spectra of organic compounds on aluminum plates were measured by illuminating the specimen continuously with a laser beam, and the results were comapred with the spectra obtained by a conventional heating method. Preliminary results obtained by a step scan FT-IR spectrometer and a modulated laser beam were also discussed.
