摘要：
Optical spectra in the near infrared region have been measured at a temperature range from 15 to 300 K. For Co3O4 the antiferromagnetic-paramagnetic transition temperature is 40K. The nature of the observed absorption bands explained in terms of electronic transitions of two-valent cobalt with the tetrahedral symmetry of the spinel lattice. The splitting of energetic levels at low temperatures is discussed.
