摘要：

Thermally detected (TD) absorption spectroscopy techniques at liquid helium temperatures are described. Electron paramagnetic resonance (EPR) and optical absorption (OA) are detected by the temperature rise of the sample due to spin-lattice relaxation or non-radiative de-excitation, which occurs after the absorption. Details on the TD EPR and TD OA cells and spectrometers are given. The usefulness and strength of the thermal detection is illustrated by a short review of the results obtained for GaAs:V and GaP:V systems.
