Applications of Laser-Induced Thermal Emission Spectroscopy to Various Samples

Abstract

The Laser-Induced Thermal Emission (LITE) spectra of several solid samples were measured and compared with the usual thermal emission spectra generated by the heating element. The following advantages in LITE spectroscopy were made clear: (1) the spectral background is reduced; (2) the time required for the stabilization of the thermal emission signal is short; (3) the compounds which are coated on background materials with complex shapes can be measured.
