摘要：

A diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) chamber suitable for in situ and simultaneous analysis of the infrared and electrical response of sensors is tested and described in detail, Experiments on a CdGeON sensor show some results about its reversible/ irreversible behavior in terms of temperature and under N-2 atmosphere. A direct relationship between the conductivity and the elimination of DRIFTS peaks at 810, 780, and 580 cm(-1) is observed. From both DRIFTS spectra and conductivity measurements, an explanation involving the presence and filling of vacancies in the solid framework is proposed.
